Since kicking off last Thursday, Fashion Week has been non-stop, and between the runways to the dinners to the after-parties, New Yorkers have been buzzing from dawn till dusk. Before Fashion Night Out kicked off the season, Proenza Schouler's Madison Avenue store opening and Brian Atwood's new ad campaign launch and the celebration of his first NYC flagship gave us a preview of the parties to come.
