Best Last-Minute Dress
Menage a Trois
799 Madison Avenue, second floor
It's two weeks and counting to your sister's wedding. With all the frenzy over her dress, you haven't thought for a second about yours. Let the couture design trio at Menage a Trois be fairy godmothers to your frantic Cinderella. Looks start at $750, and range from dupioni-silk dinner suits fit for Le Cirque to smooth-as-glass boot-cut leather pants for downtown divas. But the best part is that the staff works at warp speed. An iridescent silk-taffeta ball gown or bias-cut chiffon slip-dress, with one muslin and two regular fittings, takes two weeks. In a pinch, they can even turn a panicked phone order on Wednesday morning into a simple, perfectly fitted sheath by Friday afternoon. The shop's helpful owners know the ins and outs of frantic partygoing they'll track down the perfect Sergio Rossis, send you for an updo, and book dinner at the Brasserie without batting an eye.
