The shop Alter is the most recent retail addition to Greenpoint's Franklin Avenue, and the new boutique is the perfect showcase for the owners' mutual obsession.Three years ago, Tommy Cole and Roy Caire's started the collection This Old Thing, reworking men's vintage items into bespoke conversation pieces. Now, the newly opened storefront has been transformed into a two-room shop and an homage to their elegant recut-and-resewn line. It's filled with their deconstructed designs, like the trench that became a cropped jacket ($98), an old wooden chair sawed in half functions as an artful display with black roses. There's also a smattering of jeans and T-shirts from Cheap Monday, exclusive black diamond jewelry from This Old Thing ($120-$320), and hand-picked men's and women's vintage ($25-$100). Merchandise is added weekly, but the lot is essentially seasonless and based on what the pair find on their routine trips to the Goodwill.
