incorporated by reference in this Registration Statement constitute
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. These forward-looking statements involve known
and unknown risks, uncertainties and other factors which may cause the actual
results, performance or achievements of Iconix Brand Group, Inc. to be

                                   The Company

      Iconix is in the business of licensing the CANDIE'S(R), BONGO(R), BADGLEY
MISCHKA(R), JOE BOXER(R) and RAMPAGE(R) trademarks on a variety of young women's
footwear, apparel and fashion products. Through its wholly owned subsidiary,
Bright Star Footwear, LLC, the Company also arranges for the manufacture of
footwear products for mass market and discount retailers and receives a
commission on the sales of these products.

      Iconix was incorporated under the laws of the State of Delaware in 1978.
Its principal executive offices are located at 215 West 40th Street, New York,
New York 10018, and its telephone number is (212) 730-0300.

      Unless the context requires otherwise, reference in this prospectus to
"we", "us" ,"our", "Iconix", or "Company" refers to Iconix Brand Group, Inc. and
its subsidiaries.

                                  Risk Factors

      We operate in a changing environment that involves numerous known and
unknown risks and uncertainties that could materially adversely affect our
operations. The following highlights some of the factors that have affected, and
in the future could affect, our operations.

We have incurred losses during recent fiscal years and future losses could
negatively affect our cash flows and business operations.

      Although we recorded net income of $3.3 million for the six months ended
June 30, 2005 (including a non-cash tax benefit of $1.8 million) and $241,000 in
the 11-month period ended December 31, 2004, in the fiscal year ended January
31, 2004 we sustained net losses of $11.3 million, and net losses of $3.9
million, $2.3 million and $8.2 million during our fiscal years ended January 31,
2003, 2002 and 2001, respectively. We cannot guarantee that we will not incur
losses in the future.


                                       3


We are no longer directly engaged in the design, manufacture, distribution or
sale of branded apparel, footwear or other fashion products and, consequently,
our revenues are dependent on the success of certain licensees of those rights.

      Although the licensing agreements for our brands usually require the
advance payment to us of certain fees and provide for certain guaranteed minimum
royalty payments to us, the failure by the licensees to satisfy their
obligations under the agreements could result in the termination of the license
agreements. Moreover, during the terms of the license agreements we are
substantially dependent upon the abilities of the licensees to maintain the
quality, marketability and consumer recognition of the licensed products bearing
our brands. In addition, failure by the licensees to meet their production,
manufacturing or distribution requirements could negatively impact their sales
and resulting royalty payments to us which, in turn, would materially adversely
affect our revenues and business operations. Moreover, the failure by licensees
to meet their financial obligations to us could jeopardize our ability to meet
the debt service coverage ratio in connection with the asset-backed notes issued
by one of our subsidiaries which would give the note holders the right to
foreclose on our trademarks and other related intellectual property assets,
which are the security for the debt.

Our business is dependent on continued market acceptance of the products of our
licensees that bear our trademarks and of the CANDIE'S, BONGO, BADGLEY MISCHKA,
JOE BOXER and RAMPAGE trademarks.

      Our ability to achieve continued market acceptance of products utilizing
our trademarks as well as market acceptance of any future products that may be
offered by us or by our licensees that bear our trademarks, is subject to a high
degree of uncertainty. Our ability or the ability for our licensees to achieve
market acceptance by new customers or continued market acceptance by existing or
past customers may require substantial additional marketing efforts and the
expenditure of significant funds by us to maintain a demand for such products.
Additional marketing efforts and expenditures may not result in increased market
acceptance of products of our licensees or increased sales of such products. We
are materially dependent on the sale of products bearing our trademarks for a
significant portion of our revenues. Although our licensees guarantee minimum
net sales and minimum guaranteed royalties to us, a failure of our trademarks or
products to achieve or maintain market acceptance could reduce our licensing
revenues, thereby negatively impacting cash flows.

We had a working capital deficit at June 30, 2005, have incurred a substantial
amount of indebtedness and to the extent that cash flow from our continuing
operations is insufficient to meet our debt obligations, we may be required to
seek additional financing to satisfy our obligations or lose title to our
trademarks.


                                       4


As of the date of this prospectus there is approximately $103 million principal
outstanding on seven-year asset backed notes issued by one of our subsidiaries,
IP Holdings, LLC, referred to as IPH Holdings or IPH. The notes were issued in
four transactions, $ 20 million in August 2002, $2.6 million in March 2004, $45
million in July 2005 in connection with our acquisition of the JOE BOXER brand
from Joe Boxer, LLC and $40 million in September 2005. Of the additional debt
incurred in September 2005, $28 million was used in connection with our
acquisition of the RAMPAGE brand on September 16, 2005 and the remaining $12
million is available to us for potential future acquisitions. We will be
required to repay the $12 million on November 15, 2005 if we do not use the
funds in connection with an acquisition. The payment of the principal and
interest on the notes will be made from amounts received by IP Holdings under
license agreements with various licensees of the assets acquired and IP
Holdings' other intellectual property assets. In the event that there is a
default in the payment on the notes, the note holders have a security interest
in our trademarks and have the right to foreclose on those trademarks. In
addition, in connection with our acquisition in April 2002 from Sweet
Sportswear, Inc., referred to as Sweet, of the remaining equity interests in
Unzipped Apparel, LLC, referred to as Unzipped, the joint venture formed with
Sweet, we issued to Sweet $11.0 million principal amount of senior subordinated
notes the amount of which have been reduced to approximately $2.8 million at
June 30, 2005 as a result of certain shortfalls in the net income of Unzipped
that Sweet guaranteed under the terms of an agreement under which it managed
Unzipped until August 2004. As of the date of this prospectus we are involved in
litigation with Sweet and certain of its affiliates with respect to certain
matters pertaining to Unzipped. Moreover, we had a working capital deficit of
approximately $3.3 million at June 30, 2005. We believe that we will generate
sufficient revenues from our licensing operations to satisfy our obligations for
the foreseeable future. However, in the event that projected cash flow proves to
be insufficient to satisfy our cash requirements including our debt obligations,
we may be required to seek additional funds through, among other means, public
or private equity or debt financing, which may result in dilution to our
stockholders, or if we were to default on our obligations to the holders of the
asset backed notes they could foreclose on our trademarks.

A substantial portion of our licensing revenues are concentrated in two
retailers.

Two of our largest licenses are each concentrated at a single retailer. The
CANDIE'S brand is concentrated at Kohl's Department Stores, Inc., which by the
end of 2006 will be the exclusive licensee for all product categories, and the
JOE BOXER brand, which has an exclusive license with Kmart for all core product
categories. Because we are dependent on these two licensees for a substantial
portion of our licensing revenue, if Kohl's or Kmart (which came out of
bankruptcy in May 2003 and is currently owned by Sears Holding Corp.) had
financial difficulties or ceased to operate, it would negatively impact our
revenue and cash flows.

A recession in the fashion industry or rapidly changing fashion trends could
harm our operating results.

      The fashion industry is cyclical, with purchases of apparel and related
goods tending to decline during recessionary periods when disposable income is
low. A poor general economic climate could have a negative impact on our and our
licensees' ability to compete for limited consumer resources. Moreover, our
future success depends in substantial part on our and our licensees' ability to
anticipate and respond to changing consumer demands and fashion trends in a
timely manner. The footwear and wearing apparel industries are generally subject
to constantly changing fashion trends. If we or our licensees misjudge the
market for a particular product or product line, it may result in an increased
inventory of unsold and outdated finished goods, which could increase the
affected licensee's operating costs without a corresponding increase in
revenues.


                                       5


Our licensees are subject to risks and uncertainties of foreign manufacturing
that could interrupt operations or increase operating cost thereby impacting
their ability to deliver goods to the market.

      Substantially all of the products sold by our licensees are manufactured
overseas. We and our licensees are subject to various risks inherent in foreign
manufacturing, including fluctuations in foreign currency exchange rates;
shipping delays; and international political, regulatory, and economic
developments, all of which can have a significant impact on the licensee's
operating costs and consequently, our earnings.

      Our licensees also import certain finished products and assume all risk of
loss and damage once their suppliers ship these goods. If these goods are
destroyed or damaged during shipment it could impact our revenues as a result of
its licensees' delay in delivering finished products to customers.

Because of the intense competition in our markets and the strength of our
competitors, we and our licensees may not be able to continue to compete
successfully.

      The apparel, footwear and fashion industries are extremely competitive in
the United States and our licensees face intense and substantial competition for
our product lines. In general, competitive factors include quality, price,
style, name recognition and service. In addition, the presence in the
marketplace of various fads and the limited availability of shelf space can
affect competition. Many competitors of our licensees have greater financial,
distribution, marketing and other resources than they have and have achieved
significant name recognition for their brand names. We may not be able to
continue to compete successfully in the market with respect to the licensing
arrangements. Our licensees may be unable to successfully compete in the markets
for such products.

We may not be able to protect our proprietary rights or avoid claims that we
infringe on the proprietary rights of others.

      We own trademark registrations for CANDIE'S, BONGO, BADGLEY MISCHKA, JOE
BOXER and RAMPAGE, among others, and believe that our trademarks have
significant value and are important to the marketing of our products. To the
extent that the trademarks owned or used by us are deemed to violate the
proprietary rights of others, or in the event that these trademarks would not be
upheld if challenged, we would, in either such event, be prevented from using
the trademarks, which could have an adverse effect on us. In addition, we may
not have the financial resources necessary to enforce or defend trademarks owned
or used by us.

We are dependent upon our key executives and other personnel, whose loss would
adversely impact our business.

      Our success is largely dependent upon the efforts of Neil Cole, our
President, Chief Executive Officer and Chairman, and certain other key
executives. Although we have entered into an employment agreement with Mr. Cole
that expires in December 2007, the loss of his and/or other key executive's
services would have a material adverse effect on our business and prospects. Our
success is also dependent upon our ability to hire and retain additional
qualified sales and marketing personnel in connection with the design, marketing
and distribution of our products as well as our ability to hire and retain
administrative personnel. We may not be able to hire or retain such necessary
personnel.


                                       6


Provisions in our charter and share purchase rights plan may prevent an
acquisition of Iconix.

      Certain provisions of our Certificate of Incorporation and our Share
Purchase Rights Plan could have the effect, either alone or in combination with
each other, of making more difficult, or discouraging an acquisition of our
company deemed undesirable by our Board of Directors. Our Certificate of
Incorporation provides for the issuance of up to 75,000,000 shares of common
stock and 5,000,000 shares of preferred stock. As of the date of this prospectus
there were approximately 33,150,000 shares of our common stock and no shares of
preferred stock outstanding. Additional shares of our common stock and preferred
stock are therefore available for future issuance without stockholder approval.
The Share Purchase Rights Plan, commonly known as a "poison pill," states that,
in the event than an individual or entity acquires 15% of the outstanding shares
of our stockholders other than the acquirer may purchase additional shares of
our common stock for a fixed price. The existence of authorized but un-issued
capital stock, together with the existence of the Share Purchase Rights Plan,
could have the effect of discouraging an acquisition of us.

We are subject to certain litigation that could harm us.

      We are currently a plaintiff and cross-defendant in a litigation pending
in California state court involving Unzipped, and a defendant in a litigation
pending in federal district court in New York involving a former supplier. Our
financial condition could be adversely impacted if we are required to pay the
monetary damages sought by the cross-complainants in the California action and
the plaintiff in the New York action, or if it is adjudicated that the
contractual rights concerning Unzipped are invalid.

The market price of our common stock may be volatile.

      The market price of our common stock may be highly volatile. Among other
things, disclosures of our operating results, announcements of various events by
us or our competitors and the development and marketing of new products may
cause the market price of our common stock to change significantly over short
periods of time. Sales of shares under this prospectus may have a depressive
effect on the market price of our common stock.

Future sales of shares of our common stock could affect the market price of our
common stock and our ability to raise additional capital.

      We have previously issued a substantial number of shares of common stock,
which are eligible for resale under Rule 144 of the Securities Act of 1933, as
amended, referred to as the Securities Act, and may become freely tradable. We
have also registered a substantial number of shares of common stock that are
issuable upon the exercise of options and warrants and have previously
registered for resale a substantial number of restricted shares of common stock
held by certain selling stockholders, which are in addition to the shares of our
common stock being offered by the selling stockholders pursuant to this
Prospectus. If holders of options or warrants choose to exercise their purchase
rights and sell shares of common stock in the public market, or if holders of
currently restricted shares choose to sell such shares in the public market
under Rule 144 or otherwise, the prevailing market price for our common stock
may decline. Future public sales of shares of common stock may adversely affect
the market price of our common stock or our future ability to raise capital by
offering equity securities.

----------

(1)   The amounts do not reflect that Paul M. Buxbaum (owner of record of
      500,649 shares) and Buxbaum Company LLC (owner of record of 264,306
      shares) may each be deemed to be the beneficial owner of the shares owned
      of record by the other. The after the offering stock ownership assumes the
      sale of all of the shares being offered by both Paul M. Buxbaum and
      Buxbaum Company, LLC.

(2)   Mr. Paul M. Buxbaum, the sole manager of Buxbaum Company, LLC, has sole
      dispositive power with respect to the shares being offered by Buxbaum
      Company, LLC. and, subject to the agreement described below, sole voting
      power with respect to the shares.


                                       8


(3)   Mr. Sandford T. Waddell has sole dispositive power with respect to the
      shares being offered by the Waddell Trust dated June 21, 1995 and subject
      to the agreement described below, sole voting power with respect to the
      shares.

      The selling stockholders acquired their shares in connection with the
acquisition by Iconix of certain assets relating to the Rampage(R) brand on
September 16, 2005 and have agreed to vote the shares owned or held by record by
them in favor of matters, with certain exceptions, approved by Iconix' Board of
Directors for a vote of Iconix' stockholders until the stockholders do not own,
in the aggregate, more than 500,000 shares. They also agreed to certain
limitations on the dollar amount of the shares that they may sell in the open
market prior to June 16, 2007 without the consent of Iconix.

                              Plan of Distribution

      We have been advised that the selling stockholders, which may include
pledgees, donees, transferees or other successors-in-interest who have received
shares from the selling stockholders after the date of this prospectus, may from
time to time, sell all or a portion of the shares in privately negotiated
transactions or otherwise, at fixed prices that may be changed, at market prices
prevailing at the time of sale, at prices related to these market prices or at
negotiated prices.

      All costs, expenses and fees in connection with the registration of the
shares offered by this prospectus other than any counsel for the selling
stockholders, shall be borne by us. Brokerage costs, if any, attributable to the
sale of shares will be borne by the selling stockholders.

      The shares may be sold by the selling stockholders by one or more of the
following methods:

      o     block trades in which the broker or dealer so engaged will attempt
            to sell the shares as agent but may position and resell a portion of
            the shares as principal to facilitate the transaction;

      o     purchases by a broker or dealer as principal and resale by such
            broker dealer for its account;

      o     an exchange distribution in accordance with the rules of the
            applicable exchange;

      o     over-the counter distribution in accordance with the rules of the
            Nasdaq National Market;

      o     ordinary brokerage transactions and transactions in which the broker
            solicits purchasers;


                                       9


      o     through the writing of put or call options on the shares or other
            hedging transactions (including the issuance of derivative
            securities), whether the options or other derivative securities are
            listed on an option or other exchange or otherwise;

      o     privately negotiated transactions;

      o     a combination of any such methods of sale; and

      o     any other method permitted pursuant to applicable law.

      The transactions described above may or may not involve brokers or
dealers.

      The selling stockholders will not be restricted as to the price or prices
at which the selling stockholder may sell its shares. Sales of shares by the
selling stockholders may depress the market price of our common stock since the
number of shares which may be sold by the selling stockholder may be relatively
large compared to the historical average weekly trading of our common stock.
Accordingly, if the selling stockholders were to sell, or attempt to sell, all
of such shares at once or during a short time period, we believe such a
transaction could adversely affect the market price of our common stock.

      From time to time the selling stockholders may pledge its shares under
margin provisions of customer agreements with its brokers or under loans or
other arrangements with third parties. Upon a default by the selling
stockholders, the broker or such third party may offer and sell any pledged
shares from time to time.

      In effecting sales, brokers and dealers engaged by the selling
stockholders may arrange for other brokers or dealers to participate in the
sales as agents or principals. Brokers or dealers may receive commissions or
discounts from the selling stockholders or, if the broker-dealer acts as agent
for the purchaser of such shares, from the purchaser in amounts to be
negotiated, which compensation as to a particular broker dealer might be in
excess of customary commissions which are not expected to exceed those customary
in the types of transactions involved. Broker-dealers may agree with the selling
stockholders to sell a specified number of such shares at a stipulated price per
share, and to the extent the broker-dealer is unable to do so acting as agent
for a selling stockholder, to purchase as principal any unsold shares at the
price required to fulfill the broker-dealer commitment to such selling
stockholder. Broker-dealers who acquire shares as principal may then resell
those shares from time to time in transactions

      o     in the over-the counter market or otherwise;

      o     at prices and on terms prevailing at the time of sale;

      o     at prices related to the then-current market price; or

      o     in negotiated transactions.

      These resales may involve block transactions or sales to and through other
broker-dealers, including any of the transactions described above. In connection
with these sales, these broker-dealers may pay to or receive from the purchasers
of those shares commissions as described above. The selling stockholders may
also sell the shares in open market transactions under Rule 144 under the
Securities Act, rather than under this prospectus.


                                       10


      The selling stockholders and any broker-dealers or agents that participate
with the selling stockholders in sales of the shares may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with these
sales. In this event, any commissions received by these broker-dealers or agents
and any profit on the resale of the shares purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act.

      We have agreed to indemnify certain of the selling stockholders against
certain liabilities under the Securities Act. The selling stockholders may agree
to indemnify any agent, dealer or broker-dealer that participates in
transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act.

      The selling stockholders are subject to applicable provisions of the
Securities Exchange Act of 1934 and the SEC's rules and regulations, including
Regulation M, which provisions may limit the timing of purchases and sales of
the shares by the selling stockholders.

      In order to comply with certain states' securities laws, if applicable,
the shares may be sold in those jurisdictions only through registered or
licensed brokers or dealers. In certain states the shares may not be sold unless
the shares have been registered or qualified for sale in such state, or unless
an exemption from registration or qualification is available and is obtained.

                                  Legal Matters

      Blank Rome LLP of New York, New York will pass upon the validity of the
shares of common stock being offered by this prospectus.

Item 14. Other Expenses of Issuance and Distribution.

      The expenses payable by the Registrant in connection with the issuance and
distribution of the securities being registered (estimated except for the SEC
Registration fee)are as follows:

SEC Registration Fee                                          $ 2,164.65

Accounting Fees and Expenses                                  $ 5,000.00

Miscellaneous Expenses                                        $ 5,835.35

Total                                                         $25,000.00

Item 15. Indemnification of Directors and Officers.

      Section 145 of the General Corporation Law of the State of Delaware
("GCL") provides for the indemnification of officers and directors under certain
circumstances against expenses incurred in successfully defending against a
claim and authorizes Delaware corporations to indemnify their officers and
directors under certain circumstances against expenses and liabilities incurred
in legal proceedings involving such persons because of their being or having
been an officer or director.

      Section 102(b) of the GCL permits a corporation, by so providing in its
certificate of incorporation, to eliminate or limit director's liability to the
corporation and its shareholders for monetary damages arising out of certain
alleged breaches of their fiduciary duty. Section 102(b)(7) of the GCL provides
that no such limitation of liability may affect a director's liability with
respect to any of the following: (i) breaches of the director's duty of loyalty
to the corporation or its shareholders; (ii) acts or omissions not made in good
faith or which involve intentional misconduct of knowing violations of law;
(iii) liability for dividends paid or stock repurchased or redeemed in violation
of the GCL; or (iv) any transaction from which the director derived an improper
personal benefit. Section 102(b)(7) does not authorize any limitation on the
ability of the corporation or its shareholders to obtain injunctive relief,
specific performance or other equitable relief against directors.

      Article Ninth of the registrant's Certificate of Incorporation and the
registrant's By-laws provide that all persons who the registrant is empowered to
indemnify pursuant to the provisions of Section 145 of the GCL (or any similar
provision or provisions of applicable law at the time in effect), shall be
indemnified by the registrant to the full extent permitted thereby. The
foregoing right of indemnification shall not be deemed to be exclusive of any
other rights to which those seeking indemnification may be entitled under any
by-law, agreement, vote of shareholders or disinterested directors, or
otherwise.


                                      II-1


      Article Tenth of the registrant's Certificate of Incorporation provides
that no director of the registrant shall be personally liable to the registrant
or its stockholders for any monetary damages for breaches of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the registrant or its stockholders; (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law; (iii) under Section 174 of the GCL; or (iv) for any transaction from which
the director derived an improper personal benefit.

      The registrant's employment agreements with Mr. Neil Cole, the
registrant's Chief Executive Officer, Mr. William Sweedler, an Executive Vice
President of the registrant and Ms. Deborah Sorell Stehr, the registrant's
Senior Vice President and General Counsel generally provide that the registrant
shall indemnify each of them for the consequences of all acts and decisions made
by such person while performing services for the registrant. These agreements
also require the registrant to use its best efforts to obtain directors' and
officers' liability insurance for such persons.

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.

Item 17. Undertakings

Undertaking Required by Regulation S-K, Item 512(a).

The undersigned registrant hereby undertakes:

      (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

            i.    To include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933, as amended (the "Securities Act");

            ii.   To reflect in the prospectus any facts or events arising after
                  the effective date of the Registration Statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in the Registration Statement;


                                      II-2


            iii.  To include any material information with respect to the plan
                  of distribution not previously disclosed in the Registration
                  Statement or any material change to such information in the
                  Registration Statement;

provided, however, that clauses (i) and (ii) do not apply if the Registration
Statement is on Form S-3, Form S-8 or Form F-3, and the information required to
be included in a post-effective amendment by such clauses is contained in
periodic reports filed with or furnished to the Commission by the Registrant
pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the Registration Statement;

      (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

Undertaking Required by Regulation S-K, Item 512(b).

      The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be initial bona fide offering thereof.

Undertaking required by Regulation S-K, Item 512(h).

      Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or controlling persons pursuant to
the foregoing provisions, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
