A friend visiting from England whined, "Your vintage clothing stores are a downer. More like costume shops." So we took her to Antique Sugar and she shut the hell up. This is the place for fabulous yesteryear threads, and its expanded stock in its new location (Sugar recently relocated from midtown to groovy downtown digs) is even better than it once was — and that was pretty darn good. There we typically find couture attire, '70s garments perfect for those pesky disco parties people keep throwing, and the best selection of midcentury lounging pajamas you'll ever see. Recent impossible-but-true finds include 1940s still-in-the-box navy blue silk stockings, dyed-fabric pumps (in our size!), and a 1963 Elizabeth Arden frock coat with the tags hanging off. Also surprising is this boss boutique's wide array of men's duds, a rarity in any vintage clothing store.
