Fast-fashion giant Forever 21 might be closing three of its stores in San Diego County as part of a major corporate overhaul.

The retailer filed for Chapter 11 bankruptcy Sunday, announcing that it could potentially shutter 178 of its 548 U.S. stores. Worldwide, the brand could close as many as 350, according to bankruptcy filings.

The closure list includes stores in Mission Valley, Westfield UTC shopping mall and Parkway Plaza’s El Cajon location. The Mission Valley location is an F21 Red store, a sister-brand of Forever 21.

In total, the retailer listed 41 stores in California. Other Southern California outlets on the list are in Los Angeles, Culver City, Pasadena, Valencia, Arcadia and Newport Beach.

Once a titan of retail, Forever 21 is now being squeezed on multiple fronts. The stores are facing competition from online retailers and low foot traffic in shopping malls, along with an increasingly cold reception to its extra-cheap apparel. The retailer is also suffering from its own over expansion, often occupying large brick-and-mortar locations in major shopping malls. In its bankruptcy filing, the company said it has struggled to support its “outsized store footprint as consumers increasingly purchase clothing and other goods online.”

“This was an important and necessary step to secure the future of our company, which will enable us to reorganize our business and reposition Forever 21,” said Linda Chang, executive vice president of Forever 21, in a statement.

It’s not officially over for these stores, however. Forever 21 said in its statement that it is working to renegotiate its leases in an effort to remain open, especially in major U.S. markets.
