Bonnie Morrisson, Tim Blanks and the designers of Threeasfour were among the many fashion types who sipped Prosecco and noshed on snacks at Maria Cornejo's new boutique on 33 Bleecker Street. The word boutique, though, is an understatement. The sprawling space is unlike many other stores you'll find: beyond the label's current collections, it houses archives from previous seasons and a design studio where Cornejo and her design team work every day. The atelier features dramatic 14-foot ceilings, wooden floors and lead framed windows. But if the fixtures don't move you, I'm sure the clothes -- Cornejo's complete range of pieces all under one roof -- will.
