With a client roster that includes Kate Moss and Lady Gaga, Divine Decadence Originals clearly knows its stuff. Located in the tony Yorkville neighborhood, this vintage-couture boutique offers rack after rack of extraordinary garments, both big-name (think Valentino, Lanvin, and Chanel) and no- name (like a Bolivian embroidered-velvet jacket). No matter the piece, vivacious owner Carmelita Blondet knows its history and provenance. She buys from the original owners, not auction houses, so the items carry a special magic.
