Deborah Marquit (CLOSED)

Though lingerie designer Deborah Marquit’s incredibly sexy unmentionables are sold at stores like Barneys, you’ll want to make a special trip to her quirky boutique, which doubles as a design studio where she hand-dyes, cuts and sews every piece. Not only will you get to see a genius at work (Singer sewing machines and mannequins share space with the racks of merchandise), Marquit will personally fit you to make sure her bikini briefs ($75–$115), thongs ($5–$85), boy shorts ($95–$115), garter belts (lace $115, vinyl $185) and bras ($165–$225)—up to size 38D—adhere to every curve. The creations come in flashy fluorescent neon, jacquard daisy-print, and black vinyl, yet somehow she manages to make even the most extreme colors and fabrics look classy and tasteful.
