                                  RISK FACTORS

    PROSPECTIVE  PURCHASERS OF THE  COMMON STOCK OFFERED  HEREBY SHOULD CONSIDER
CAREFULLY THE FACTORS SET FORTH BELOW, AS WELL AS OTHER INFORMATION SET FORTH IN
THIS  PROSPECTUS,  IN  EVALUATING  AN  INVESTMENT  IN  THE  COMMON  STOCK.  THIS
PROSPECTUS   CONTAINS  FORWARD-LOOKING   STATEMENTS  WHICH   INVOLVE  RISKS  AND
UNCERTAINTIES. THE COMPANY'S  ACTUAL RESULTS  AND THE TIMING  OF CERTAIN  EVENTS
COULD   DIFFER  MATERIALLY  FROM  THOSE   ANTICIPATED  BY  SUCH  FORWARD-LOOKING
STATEMENTS AS  A  RESULT  OF  CERTAIN  FACTORS  DISCUSSED  IN  THIS  PROSPECTUS,
INCLUDING  THE  FACTORS  SET FORTH  BELOW  AND IN  "MANAGEMENT'S  DISCUSSION AND
ANALYSIS OF FINANCIAL CONDITION  AND RESULTS OF  OPERATIONS" AND "BUSINESS,"  AS
WELL AS THOSE DISCUSSED ELSEWHERE IN THIS PROSPECTUS.
 
COMPETITION AND OTHER FACTORS AFFECTING THE APPAREL AND RETAILING INDUSTRIES
 
    The  apparel  industry  is  highly competitive,  fragmented  and  subject to
rapidly changing consumer demands and preferences. The Company believes that its
success depends in large part upon its ability to anticipate, gauge and  respond
to  changing consumer demands and fashion trends in a timely manner and upon the
continued appeal to  consumers of  the Guess image.  Failure by  the Company  to
identify  and  respond appropriately  to changing  consumer demands  and fashion
trends could adversely affect consumer acceptance of Guess products and may have
a material adverse effect  on the Company's financial  condition and results  of
operations.  Guess competes with numerous apparel manufacturers and distributors
(including Calvin  Klein,  Ralph  Lauren, DKNY,  Tommy  Hilfiger  and  Nautica).
Moreover,  several well-known designers have  recently entered or re-entered the
designer denim market with  products generally priced  lower than the  Company's
designer   jeans  products.  Guess's  retail  and  factory  outlet  stores  face
competition  from  other   retailers.  Additionally,   the  Company   encounters
substantial  competition from department stores, including some of the Company's
major retail customers. Many of the Company's competitors have greater financial
resources than  Guess.  The  Company's licensed  apparel  and  accessories  also
compete  with a substantial number of  designer and non-designer lines. Although
the level and nature of competition  differ among its product categories,  Guess
believes  that it competes primarily on the basis of its brand image, quality of
design and workmanship and product assortment. Increased competition by existing
and future competitors could  result in reductions in  sales or prices of  Guess
products  that could have  a material adverse effect  on the Company's financial
condition  and  results  of  operations.  In  addition,  the  apparel   industry
historically  has  been  subject  to  substantial  cyclical  variations,  and  a
recession in  the general  economy or  uncertainties regarding  future  economic
prospects  that affect  consumer spending habits  could have  a material adverse
effect on the Company's financial condition and results of operations.
 
DEPENDENCE UPON CERTAIN CUSTOMERS AND LICENSEES
 
    The  Company's  department  store  customers  include  major  United  States
retailers.  The Company's  three largest  customers accounted  for approximately
26.0% of net revenue in 1995. During 1995, Bloomingdale's, Macy's and affiliated
stores owned by Federated Department Stores together accounted for approximately
11.0% of the Company's net revenue; The May Company accounted for  approximately
7.7%   of  the  Company's  net  revenue;  and  Dillard's  stores  accounted  for
approximately 7.3%  of  the  Company's  net revenue.  Although  several  of  the
Company's department store customers are under common ownership, no other single
customer  or group  of related  customers accounted  for more  than 3.0%  of the
Company's net revenue in this period. While the Company believes that purchasing
decisions in many cases  are made independently by  each department store  chain
under  common ownership,  the trend  may be  toward more  centralized purchasing
decisions. A decision by the controlling  owner of a group of department  stores
or  any other  significant customer  to decrease  the amount  purchased from the
Company or to cease carrying Guess products could have a material adverse effect
on the  Company's financial  condition  and results  of operations.  The  retail
industry has periodically experienced consolidation and other ownership changes.
In  the  future,  the  Company's wholesale  customers  may  consolidate, undergo
restructurings or reorganizations, or realign  these affiliations, any of  which
could  decrease the number of stores that  carry the Company's or its licensees'
products or increase  the ownership  concentration within  the retail  industry.
Approximately 48.1% of the Company's net royalties was derived from its top four
licensed  product lines, GUESS WATCHES (18.9% of 1995 net royalties), BABY GUESS
(12.3%), GUESS KIDS (9.2%)  and GUESS EYEWEAR (7.7%).  The BABY GUESS and  GUESS
KIDS  lines are licensed to  the same entity. A  substantial portion of sales of
GUESS brand  products by  its licensees  are also  made to  the Company's  three
largest    customers.    The    inability   of    the    Company    to   control
 
                                       8

the quality, focus, image or distribution of its licensed products could  impact
consumer  receptivity  to  the  Company's  products  generally  and,  therefore,
adversely affect the Company's financial condition and results of operations.
 
RISKS ASSOCIATED WITH ACHIEVING AND MANAGING GROWTH
 
    To manage  growth  effectively,  Guess  will  be  required  to  continue  to
implement  changes in  certain aspects of  its business, continue  to expand its
information systems and operations to  respond to increased demand, attract  and
retain qualified personnel (including management), and develop, train and manage
an  increasing  number  of  management-level  and  other  employees.  Failure to
continue  to  enhance  operating  control  systems  or  unexpected  difficulties
encountered  during  expansion could  adversely  affect the  Company's financial
condition and results of operations.
 
    As part of its operating strategy,  Guess intends to continue to expand  its
network  of retail stores.  Factors beyond the Company's  control may affect the
Company's ability to expand, including general economic and business  conditions
affecting  consumer spending. The  actual number and  type of such  stores to be
opened  and  their  success  will  depend  on  various  factors,  including  the
performance  of the Company's wholesale and retail operations, the acceptance by
consumers of the Company's retail concepts, the ability of the Company to manage
such expansion  and hire  and  train personnel,  the availability  of  desirable
locations  and  the negotiation  of acceptable  lease  terms for  new locations.
Certain of these factors are also beyond the Company's control.
 
    In addition,  Guess's strategy  relies  heavily upon  its ability  to  align
itself  with  effective  distributors and  licensees  that are  able  to deliver
high-quality products consistent with the GUESS brand image in a timely  fashion
and  to successfully integrate  such distributors and  licensees into its global
distribution channels. A general failure by the Company to maintain and  control
its  existing distribution and  licensing arrangements or  to procure additional
distribution and licensing  relationships could adversely  affect the  Company's
growth  strategy, which could adversely affect the Company's financial condition
and results of operations.
 
    The Company's strategic plan for its  wholesale division depends in part  on
its  ability  to  expand its  sales  to international  distributors,  deepen its
product offerings and expand and upgrade its shop-in-shop program. This strategy
is subject to a number of factors beyond the Company's control including general
economic conditions and  changing consumer preferences.  Between 1992 and  1995,
net  revenue from wholesale operations decreased  32%. There can be no assurance
that the Company's business strategy will be successful in halting or  reversing
this decline in net revenue.
 
DEPENDENCE UPON KEY PERSONNEL
 
    The  success of  Guess is  largely dependent  upon the  personal efforts and
abilities of its senior management, particularly Mr. Maurice Marciano,  Chairman
of the Board and Chief Executive Officer, Mr. Paul Marciano, President and Chief
Operating  Officer, and Mr. Armand Marciano, Senior Executive Vice President and
Secretary. Effective  upon  consummation of  the  Offerings, Maurice,  Paul  and
Armand  Marciano will continue to beneficially own  an aggregate of 83.6% of the
Company's  outstanding  Common  Stock  and  each  will  enter  into   employment
agreements with the Company. Although the Company has recently recruited several
key  executives with  substantial industry expertise,  the extended  loss of the
services of  one  or more  of  the Principal  Executive  Officers could  have  a
material  adverse  effect  on the  Company's  operations. The  Company  does not
currently have "key man" insurance with respect to any of such individuals.  See
"Management -- Employment Agreements."
 
FOREIGN OPERATIONS AND SOURCING; IMPORT RESTRICTIONS
 
    During  1995, approximately 18% of the Company's purchases of raw materials,
labor and finished goods for its apparel were made in Hong Kong and other  Asian
countries;  approximately 4%  were made  in Europe;  approximately 1%  were made
elsewhere outside the United  States; and the  balance of 77%  were made in  the
United  States, all through arrangements with independent contractors. In recent
years, Guess has been increasing its  sourcing of fabrics outside of the  United
States.  In addition, Guess has been  increasing its international sales and, in
1995, approximately 5.0% and 1.9% of the Company's net revenue was from  product
sales  to  customers in  international markets  and from  net royalties  paid by
international
 
                                       9

licensees, respectively. As a result,  the Company's operations may be  affected
adversely by political instability resulting in the disruption of trade with the
countries  in  which  the  Company's  contractors,  suppliers  or  customers are
located, the  imposition  of additional  regulations  relating to  imports,  the
imposition of additional duties, taxes and other charges on imports, significant
fluctuations   in  the  value  of  the  dollar  against  foreign  currencies  or
restrictions on the  transfer of funds.  The inability of  a contractor to  ship
orders  in a  timely manner could  cause the  Company to miss  the delivery date
requirements  of  its  customers  for   those  items,  which  could  result   in
cancellation  of orders,  refusal to accept  deliveries or a  reduction in sales
prices. Further, since Guess is unable  to return merchandise to its  suppliers,
it  could be faced with a significant  amount of unsold merchandise, which could
have a material adverse effect on the Company's financial condition and  results
of operations.
 
    Sovereignty  over Hong Kong  is scheduled to be  transferred from the United
Kingdom to  The  People's Republic  of  China effective  July  1, 1997.  If  the
business  climate in Hong Kong were to  experience an adverse change as a result
of the  transfer, the  Company believes  it could  relocate its  production  and
sourcing  facilities  outside Hong  Kong and  replace the  merchandise currently
produced in Hong  Kong with  merchandise produced elsewhere  without a  material
adverse  effect on the  Company's financial condition  or results of operations.
Nevertheless, there can be no assurance that the Company would be able to do so.
 
    The Company's  import  operations  are subject  to  constraints  imposed  by
bilateral  textile agreements between the United  States and a number of foreign
countries, including Hong Kong, China, Taiwan and South Korea. These agreements,
which have been negotiated bilaterally either under the framework established by
the  Arrangement  Regarding  International  Trade  in  Textiles,  known  as  the
Multifiber Agreement, or other applicable statutes, impose quotas on the amounts
and types of merchandise which may be imported into the United States from these
countries. These agreements also allow the United States to impose restraints at
any  time  and  on  very  short  notice  on  the  importation  of  categories of
merchandise that, under the terms of  the agreements, are not currently  subject
to specified limits. Imported products are also subject to United States customs
duties  which comprise  a material  portion of  the cost  of the  merchandise. A
substantial increase  in customs  duties could  have an  adverse effect  on  the
Company's  financial condition or  results of operations.  The United States and
the countries in  which the Company's  products are produced  or sold may,  from
time  to  time, impose  new quotas,  duties, tariffs  or other  restrictions, or
adversely adjust prevailing  quota, duty or  tariff levels, any  of which  could
have  a material adverse effect on  the Company's financial condition or results
of operations.
 
DEPENDENCE ON UNAFFILIATED MANUFACTURERS
 
    The Company does not own or operate any manufacturing facilities other  than
cutting,  silk-screen and embroidery machinery,  and is therefore dependent upon
independent contractors  for  the manufacture  of  its products.  The  Company's
products   are  manufactured  to   its  specifications  by   both  domestic  and
international manufacturers.  The  inability  of  a  manufacturer  to  ship  the
Company's products in a timely manner or to meet the Company's quality standards
could  adversely  affect  the  Company's  ability  to  deliver  products  to its
customers in a timely manner. Delays in delivery could result in missing certain
retailing seasons with respect to some or all of the Company's products or could
otherwise have  an  adverse effect  on  the Company's  financial  condition  and
results  of operations. The  Company does not have  long-term contracts with any
manufacturers.
 
    The Company  conducts  a program  to  monitor  the labor  practices  of  its
independent  contractors; however, the Company does not control such contractors
or their labor practices.  This program was implemented  in 1992 pursuant to  an
agreement  with  the federal  Department  of Labor  (the  "DOL") in  response to
concerns regarding  minimum  wage  and  overtime  payments  by  certain  of  the
Company's  contractors.  In connection  with  such agreement,  the  Company paid
approximately $559,000 to the DOL in  settlement of a minimum wage and  overtime
claim  on  behalf  of the  workers  of  two of  the  Company's  contractors. The
California Labor Commissioner (the "CLC") and the DOL regularly investigate  the
labor practices of apparel manufacturers. Recently, the Company has become aware
of  a  CLC  investigation  of  a  number  of  clothing  contractors  located  in
California, some of whom  may be producing goods  for the Company. Although  the
Company  has not received a report from the CLC identifying any of the Company's
 
                                       10

contractors involved in such investigation, the Company believes that several of
the approximately seventy contractors used by  the Company are subjects in  such
investigation. If it is determined that one or more of the Company's contractors
has  engaged in labor practices that violate the Company's policies, the Company
would  expect  to  terminate  its  relationship  with  such  contractors   under
appropriate  circumstances.  No assurance  can  be given  that  any terminations
resulting from  investigations  of this  type  would not  adversely  affect  the
Company's  ability to deliver products to its customers in a timely manner. Over
the past three years, the Company  has terminated contractors due to  violations
of  the Company's  policies. Violations of  state or federal  labor standards by
contractors engaged by the Company can result in the Company becoming subject to
monetary and/or injunctive  sanctions. Based upon  the information available  to
the Company at this time with respect to the aforementioned investigation by the
CLC,  the Company does  not believe that  such investigation will  result in the
imposition of any sanctions that would  have a material adverse effect upon  the
Company.
 
PROTECTION OF TRADEMARKS
 
    Guess  believes  that  its  trademarks  and  other  proprietary  rights  are
important to  its  success  and its  competitive  position.  Accordingly,  Guess
devotes  substantial  resources  to  the  establishment  and  protection  of its
trademarks on a worldwide  basis. Nevertheless, there can  be no assurance  that
the  actions taken by  the Company to  establish and protect  its trademarks and
other proprietary rights will be adequate  to prevent imitation of its  products
by  others or to prevent others from seeking to block sales of Guess products as
violative of the trademarks and proprietary  rights of others. No assurance  can
be  given that others will not assert rights in, or ownership of, trademarks and
other proprietary rights  of Guess.  In addition,  the laws  of certain  foreign
countries do not protect proprietary rights to the same extent as do the laws of
the United States. See "Business -- Trademarks."
 
FUTURE SALES BY PRINCIPAL STOCKHOLDERS; SHARES ELIGIBLE FOR FUTURE SALE
 
    The  Common Stock offered hereby will be  freely tradeable (other than by an
"affiliate" of the  Company as such  term is  defined in the  Securities Act  of
1933,  as amended  (the "Securities  Act")) without  restriction or registration
under the Securities  Act. Immediately  after the  Offerings, Maurice  Marciano,
Paul  Marciano and  Armand Marciano  will beneficially  own approximately 38.4%,
31.3% and 13.9%, respectively, of the  outstanding Common Stock. Subject to  the
restrictions  set forth below,  the Principal Stockholders will  be free to sell
such shares from time to time  to take advantage of favorable market  conditions
or  for any other reason. Future sales of  shares of Common Stock by the Company
and its stockholders could adversely affect  the prevailing market price of  the
Common  Stock. Guess  and the Principal  Stockholders have  entered into lock-up
agreements with Merrill  Lynch, Pierce,  Fenner &  Smith Incorporated  ("Merrill
Lynch")  and Morgan Stanley  & Co. Incorporated, as  representatives of the U.S.
Underwriters (the "U.S. Representatives"), and with Merrill Lynch  International
and  Morgan  Stanley  & Co.  International  Limited, as  representatives  of the
International Managers (the "International  Representatives" and, together  with
the  U.S. Representatives, the "Representatives"), pursuant to which the Company
and the Principal Stockholders have  agreed, subject to certain exceptions,  not
to,  directly or indirectly, (i) sell, grant any option to purchase or otherwise
transfer or  dispose of  any  Common Stock  or  securities convertible  into  or
exchangeable  or exercisable for  Common Stock or  file a registration statement
under the Securities Act with  respect to the foregoing  or (ii) enter into  any
swap  or other agreement or transaction that transfers, in whole or in part, the
economic consequence of ownership of the Common Stock, without the prior written
consent of  Merrill Lynch,  for a  period of  180 days  after the  date of  this
Prospectus.  After such  time, approximately  35,681,819 shares  of Common Stock
will be eligible for sale pursuant to Rule 144 promulgated under the  Securities
Act.   In  addition,  the  Principal  Stockholders  have  rights  to  demand  or
participate in  future  registrations  of  shares  of  Common  Stock  under  the
Securities  Act.  Sales of  substantial amounts  of Common  Stock in  the public
market, or  the perception  that such  sales may  occur, could  have a  material
adverse effect on the market price of the Common Stock. See "Shares Eligible for
Future Sale" and "Underwriting."
 
CONTROL BY PRINCIPAL STOCKHOLDERS
 
    Following the consummation of the Offerings, the Principal Stockholders will
have  majority control of the Company and the ability to control the election of
directors and the results of other matters submitted to a vote of  stockholders.
Such  concentration  of ownership,  together with  the anti-takeover  effects of
certain
 
                                       11

provisions in  the  Delaware  General  Corporation  Law  and  in  the  Company's
Certificate  of Incorporation  and Bylaws,  may have  the effect  of delaying or
preventing a  change in  control of  the Company.  See "Description  of  Capital
Stock."  The  Board of  Directors of  the  Company is  expected to  be comprised
entirely of  designees  of  the Principal  Stockholders.  See  "Management"  and
"Principal Stockholders."
 
ABSENCE OF PUBLIC MARKET AND POSSIBLE VOLATILITY OF STOCK PRICE
 
    Prior  to the  Offerings, there  has been  no public  market for  the Common
Stock, and there can be no assurance that an active trading market will  develop
or  be sustained. The initial public offering  price of the Common Stock offered
hereby will be determined through negotiations among the Company, the  Principal
Stockholders  and the Representatives and may bear no relationship to the market
price for the  Common Stock after  the Offerings. Subsequent  to the  Offerings,
prices  for  the  Common Stock  will  be determined  by  the market  and  may be
influenced by a number of factors,  including depth and liquidity of the  market
for the Common Stock, investor perceptions of the Company, changes in conditions
or  trends  in  the Company's  industry  or  in the  industry  of  the Company's
significant customers, publicly traded comparable companies and general economic
and other conditions. See "Underwriting."
 
DILUTION
 
    The initial  public offering  price is  substantially higher  than the  book
value  per share of Common Stock. Investors purchasing shares of Common Stock in
the Offerings will therefore incur immediate and substantial dilution of  $17.86
per share. See "Dilution."
