EXCLUSIVE AT NET-A-PORTER. Michael Halpern takes cues from his mother's tales of '70s discos, so it's not difficult to imagine this kaftan on the dance floor at Studio 54. Made from swathes of chiffon, this one-sleeve style is patterned with painterly brushstrokes that recall the wings of a bird. Shown here with: [Miu Miu Shoulder Bag id1219552], [Amina Muaddi Sandals id1137042], [Kenneth Jay Lane Earrings id1205600].
