THE WET SEAL ANNOUNCES JANUARY,

FOURTH QUARTER SALES

FOOTHILL RANCH, CA, February 5, 2004 — Specialty retailer The Wet Seal, Inc. (Nasdaq: WTSLA) today reported net sales for the four-week period, ended January 31, 2004, of $23.6 million, bringing sales for the fourth fiscal quarter to $148.3 million. This compares with net sales of $28.7 million for the four-week period, ended February 1, 2003, and $161.2 million for the fourth quarter a year ago. Comparable store sales for January this year declined 21.4 percent, versus a comparable store sales decline of 25.1 percent for January last year. For the fourth quarter, comparable store sales decreased 9.6 percent, compared to a decline of 18.0 percent a year ago.

Net sales for the current fiscal year, ended January 31, 2004, totaled $534.0 million, compared with $608.5 million for the prior year, ended February 1, 2003, reflecting a decline in comparable store sales of 16.3 percent for the year. This compares to a decrease in comparable store sales of 5.6 percent last year.

“While we had anticipated January to be a weaker month, sales were softer than expected, as severe winter weather reduced mall traffic,” said chief executive officer, Peter D. Whitford. “However, as we head into the Spring selling season, we are encouraged by a year-over-year decline in our inventory level. Under our ongoing aggressive markdown program, we have been effective in clearing older merchandise to make room for fresh spring merchandise, which has already begun rolling out to the stores. We look forward to making progress in improving comparable store sales trends as the year unfolds, particularly as we move into the 2004 back to school period.”

The Company noted that it still anticipates reporting a net loss for the fourth quarter of between $0.44 and $0.49 per diluted share, before the Zutopia write down. This includes a $1.28 million lawsuit settlement to store managers. The quarter will also include the previously announced pre-tax non-cash charge of approximately $5.5 million, or approximately $0.12 per diluted share, to reflect the write down of fixed assets at the Zutopia stores to their estimated fair value.

The Company continues to operate with no debt outstanding and expects its cash and investment balance for the quarter just ended to be slightly lower than the balance at the end of the third quarter. Inventory, on a square foot basis, at fiscal year end is expected to represent a decrease of approximately 6 percent from the prior year’s level.

Financial results for the fourth fiscal quarter and full year are scheduled to be released on March 18, 2004. The Company expects to hold a conference call later that day to discuss fiscal 2003 results.
