So far there are five Forth & Towne locations, one in West Nyack, NY, outside of New York City and four in the Chicago area. Gap debuted the chain in August.

Gap executives have not specified how many Forth & Towne store they plan to roll out overall, but have confirmed that the chain will be a big part of the company's business going forward. "Targeting this age group was the next natural step in expanding our portfolio," said Alan Johnson, Gap's chief financial offer, at the National Retail Federation's annual convention, in January.

Gap plans to open about 175 stores this year across all of its brands, most of which will be part of the Old Navy chain. The company also plans 135 closures, a majority of them Gap stores. Other than its five Forth & Townes, the retailer operated 1,402 Gaps, 495 Banana Republics and 958 Old Navys across the country as of the end of January. Gap also had 257 international units.
