                      Non-Employee Directors' Stock Option Program
                      Registration Statement on Form S-8

Ladies and Gentlemen:

     We have represented Chico's FAS, Inc. (the "Company") in connection with
the Company's Registration Statement on Form S-8 (the "S-8 Registration
Statement") relating to the offering by the Company (the "Offering") of an
additional 15,000 shares of the Company's Common Stock under the Company's
Non-Employee Directors' Stock Option Program (the "Plan"). This opinion is being
provided as Exhibit 5 to the S-8 Registration Statement.

     In our capacity as counsel to the Company in connection with the S-8
Registration Statement and the Offering, we have examined and are familiar with:
(1) the Company's Articles of Incorporation and Bylaws, each as currently in
effect, (2) the Plan, (3) the S-8 Registration Statement and (4) such other
corporate records and documents and instruments as in our opinion are necessary
or relevant as the basis for the opinions expressed below.

     As to various questions of fact material to our opinion, we have relied
without independent investigation on statements or certificates of officials and
representatives of the Company, the Department of State of the State of Florida
and others. In all such examinations, we have assumed the genuineness of all
signatures on original and certified documents and the conformity to original
and certified documents of all copies submitted to us as conformed, photostatic
or other exact copies.

     We express no opinion as to the law of any jurisdiction other than of the
State of Florida and the federal laws of the United States of America.

     Based upon and in reliance on the foregoing, we are of the opinion that:
