Alexa Chung.

Fashion’s Night Out took New York City by storm, and FabSugar went to all of the hottest parties! We caught up with Claire Danes and Jessica Szohr at Saks Fifth Avenue, Alexa Chung downtown at Madewell, Jessica Alba at Ralph Lauren, and Mary Kate and Ashley Olsen at the Elizabeth and James Pop-Up Shop. Watch to see all of the action!
