Can you say khaki? The throngs of the hip, happening young people crowding the Gap certainly can. In fact, one might imagine that the company invented the long-time fashion staple and the accompanying neutral color palette of clothes that perfectly match the celebrated pant. The store teems with active, energetic men and women who look to be fresh from a casting call for the store's latest ultra-cool commercial. Equally fit clerks--indistinguishable from the customers but for the tiny headsets attached to their ears--sail back and forth between the seeming sameness of men's and women's sections.
