Cassie Knight is a proud fashionista many of whose life milestones have revolved around shopping. She went to Emerson College, for example, partly for its proximity to Newbury Street, and supports her shopping habit with a job at ultra-swank consignment shop The Closet—on Newbury Street. She also worked for uber-hip streetwear retailer Karmaloop, helping open its first store (on Newbury Street, of course). When she’s not looking for the perfect little black dress, you can find her sipping a Jackie O at Upstairs on the Square. Her favorite Boston secret: the free cherry pie on Presidents' Weekend at the Cambridge Antique Market.
