Gap’s concept stores for female baby boomers are being shuttered after 18 months of lackluster sales. Forth & Towne opened 19 stores to attract older women with personal service, chic but comfy fashions, matching accessories, large dressing rooms, and bottled water. But the stores didn’t catch on and after the removal of Gap’s CEO last month the company needs to refocus its established, but suffering, Gap and Old Navy brands.
