Welcome to CSA First Look, a showcase for new stores and formats. This inaugural edition spotlights the first physical store of hot Internet start-up Birchbox, the 800,000 members and growing beauty subscription company. Located in Manhattan's SoHo, the duplex-styled, 4,500-sq.-ft. store combines the hottest new products with beauty services and weekly make-up classes. Similar to the Birchbox web site, the store puts a big emphasis on expert advice and reader reviews, offered via the touchcreens and iPads located throughout the space.
