Kiki de Montparnasse (CLOSED)

If you are ready to make a serious—and we mean serious—investment in your collection of unmentionables, there are few destinations more glamorous than Kiki de Montparnasse. Try to get past the price tags without collapsing on the floor (a $375 cage bra is on the low end of the scale), and you’ll bear witness to some utterly beautiful, quietly seductive pieces, from lingerie sets to boudoir dresses and kimono robes. Acccessorize with one of the shop’s luxurious “instruments of pleasure,” such as a pair of leather handcuffs or a sculptural vibrator.
