This black-and-crimson chain has already conquered France, and is now saturating major U.S. cities. A huge roster of perfumes is arranged alphabetically down the walls, and the comprehensive makeup selection ranges from Urban Decay to Stila to Sephora's own brand. Skin-care lines include hard-to-find names such as Peter Thomas Roth. Most important, try-on stations, complete with tissues, cotton pads, makeup remover, and disinfectant, make trying on the goods a low-commitment proposition.
