No, not the goddamn Lower East Side. It's the UPPER EAST SIDE, where all the rich old ladies go to die. That's when you get to paw through their amazing clothes, and buy them at a fraction of the cost. Don't be a snob—the shops might look full of mothballs from the outside, but once you get in the front door . . . ahhh. Make an afternoon of it, then walk down Madison Avenue and laugh at all the people paying retail. Try Encore, Bis, Michael's, La Boutique Resale, and Designer Resale, all located between 80th and 86th streets, from Madison to Third avenues.
