Los Angeles, CA, May 11, 2006 - Guess?, Inc. (NYSE:GES) today reported strong
financial results for the first quarter ended April 1, 2006.

For the first quarter of 2006, the Company reported net earnings of $15.4
million, or diluted earnings of $0.34 per share, compared to net earnings of
$8.2 million, or diluted earnings of $0.18 per share, for the first quarter of
2005.

Paul Marciano, Co-Chairman and Co-CEO, commented, "Our performance in the period
exceeded our expectations and was driven by earnings growth in all of our
business segments. Our retail business' strong comp performance contributed to
significant profit growth in the period. This momentum accelerated in April with
a comp sales increase of 22.6%. Our European business delivered earnings growth
in excess of 30% for the quarter. Our licensing business also posted strong
earnings growth of over 30%, driven by the success of sales of accessories
worldwide, including incremental business in Europe. During the quarter, we
managed the business efficiently with solid margins and effective expense
control, which contributed to a significant operating margin expansion."

Paul Marciano continued, "We are pleased that our revenues and earnings continue
to become more diversified geographically as we execute our strategy to build
the Guess? brand in North America, Europe and around the world. We believe that
we are well positioned for profitable, consistent growth and we remain confident
about our future prospects."

first quarter, a 19.3% increase from $116.5 million reported in the same period
