       NET INCOME INCREASES 54%, EXCEEDS CONSENSUS EPS ESTIMATES BY $.02,
                         YEAR TO DATE NET INCOME UP 73%

        ANAHEIM, CA/NOVEMBER 10, 2003 --- Pacific Sunwear of California, Inc.
(NASDAQ:PSUN) reported today that net income for the third quarter of fiscal
2003 was $24.5 million, or $.32 per share, basic, and $.31 per share, diluted,
an increase of 54% over net income of $15.9 million, or $.22 per share, basic,
and $.21 per share, diluted, for the third quarter of fiscal 2002.

        Sales for the third quarter of fiscal 2003 were $281.3 million, an
increase of 23.3% over sales of $228.2 million for the third quarter of fiscal
2002. Company same-store sales increased 13.8% for the third quarter of fiscal
2003 with PacSun same-store sales up 13.2% and d.e.m.o. same-store sales up
19.9%.

        "I am very proud of the Company's successes during the first nine months
of fiscal 2003. We have made great strides in all product areas and expect to
have significant improvement in sales per square foot and operating margin in
2003. For the fourth quarter of fiscal 2003, the Company is comfortable with the
mean consensus earnings per share estimate of analysts of $.37, and is based on
our assumption of a 5-6% same store sales increase for the quarter. We enter
Holiday 2003 feeling very good about our assortments. For fiscal 2004, our
guidance is for 20% earnings growth over fiscal 2003. In 2003, d.e.m.o. has
become a strong second concept that in no way erodes our core business. We
remain very much on track to grow to 1,400 stores by the end of 2007, which will
incorporate 1,000 PacSun stores and 400 d.e.m.o. stores", stated Greg Weaver,
Chairman and Chief Executive Officer.

        Net income for the first nine months of fiscal 2003 was $45.9 million,
or $.60 per share, basic, and $.59 per share, diluted, an increase of 73% over
net income of $26.5 million, or $.36 per share, basic, and $.35 per share,
diluted, for the first nine months of fiscal 2002. Sales for the first nine
months of fiscal 2003 were $714.0 million, an increase of 22.9% over sales of
$580.8 million for the first nine months of fiscal 2002. Company same-store
sales increased 13.7% for the first nine months of fiscal 2003 with PacSun
same-store sales up 12.4% and d.e.m.o. same-store sales up 25.5%.

earnings growth of 20%, the potential for 1,400 stores by fiscal 2007 are
