HOOKED ON CLASSICS Cameron Silver's Decades boutique has been a haven for stylists, celebs and vintage junkies hooked on Pucci and Courrèges. Now the vintage outpost has opened a gallery dedicated to showcasing lesser-known designers from the '60s and '70s. March's exhibit features Holly Harp, a favorite from the '70s who designed clothes for Goldie Hawn, Diana Ross, Barbra Streisand and Anjelica Huston. These days, Courtney Love and Cameron Diaz are hardcore Harp fans and although most items are for sale, you'll have to move fast to beat the stylists.
