Houston, Texas  77081

Ladies and Gentlemen:

         We have acted as counsel to The Men's Wearhouse, Inc., a Texas
corporation (the "Registrant"), in connection with the registration under the
Securities Act of 1933 of $130,000,000 principal amount of the Registrant's
3.125% Convertible Senior Notes due 2023 (the "Notes") and 3,031,431 shares of
the Registrant's common stock, par value $.01 per share, which are issuable upon
conversion of the Notes (the "Shares"), as described in the Registrant's
Registration Statement on Form S-3, Registration No. 333-111227, filed with the
Securities and Exchange Commission with respect to the Notes and the Shares, as
amended (the "Registration Statement").

         In connection therewith, we have examined the Registration Statement,
originals or copies certified or otherwise identified to our satisfaction of the
Restated Articles of Incorporation of the Registrant, as amended, the amended
By-laws of the Registrant, the corporate proceedings with respect to the
offering of the Notes, communications of public officials and such other
documents and instruments as we have deemed necessary or appropriate for the
expression of the opinions contained herein. We have assumed the authenticity
and completeness of all records, certificates and other instruments submitted to
us as originals, the conformity to original documents of all records,
certificates and other instruments submitted to us as copies, the authenticity
and completeness of the originals of those records, certificates and other
instruments submitted to us as copies and the correctness of all statements of
fact contained in all records, certificates and other instruments that we have
examined.

         Based upon the foregoing, and having regard for such legal
considerations as we deem relevant, we are of the opinion that:

         (i) the Notes have been duly authorized and constitute valid and
binding obligations of the Registrant, enforceable against the Registrant in
accordance with their terms except as such enforceability may be limited by (A)
bankruptcy, insolvency, reorganization, moratorium or

                                      -1-


similar laws affecting the enforcement of creditors' rights generally, (B)
general principles of equity (regardless of whether enforceability is considered
in an action at law or suit in equity), including the availability of equitable
remedies, (C) procedural requirements of law applicable to the exercise of
creditors' rights generally, and (D) judicial discretion inherent in the forum
addressing enforceability, and

         (ii) the Shares are duly authorized and when issued upon conversion of
the Notes in accordance with the terms of the Notes and the Indenture, dated as
of October 21, 2003, among the Registrant and JPMorgan Chase Bank, as trustee,
will be legally issued, fully paid and nonassessable.

         The opinions expressed herein relate solely to, are based solely upon
and are limited exclusively to the laws of the State of Texas, the State of New
York and the federal laws of the United States of America, to the extent
applicable. We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Prospectus included as part of the Registration Statement.



                                        Very truly yours,

                                        /s/ Fulbright & Jaworski L.L.P.
