C. Madeleine's

This 10,000-square-foot space on a nondescript stretch 
of Biscayne Boulevard is the improbable home of the best vintage collection in the U.S.—we’re talking Edwardian slips, Thierry Mugler power suits, pristine-condition design pieces and one boutique dedicated entirely to Chanel. Don’t go looking for bargains—the staff maintains an incredibly high level of curation, with the price tags to match. Even so, we’ve got our eye on a pair of Bertoia diamond chairs with their original seat pads—not a steal, but gorgeous investment pieces, starting at $600.
