Buffalo Exchange

Sell or trade your used clothes, accessories and jewelry at this stocked-to-the-gills Williamsburg favorite—but don't be offended if they pass up your Gap sweatshirt and Old Navy leggings in favor of the vintage Yves St. Laurent dress being hawked by the girl in line behind you. The discerning buyers choose carefully to ensure that this is not just another hand-me-down store, although at this point—with more than 33 stores in 13 states—it's definitely a chain.
