In the wake of Hurricane Sandy, stylists, celebrities and style-minded shoppers alike venture out Wednesday evening to sip cocktails and shop for charity. Despite the slippery snow, the Fashion For Action opening night fundraiser is alive with energy. Surrounding a bustling open bar, shelves and racks of merchandise donated from over 250 brands--including Tory Burch, Diane Von Furstenberg, Brooks Brothers, and Theory--are being sold at significant discount by Housing Works Wednesday night inside the Altman building and through the end of the week at the Housing Works in Chelsea.
