BIS Designer Resale

Keep an eagle eye on Bis because every other day this secondhand clothing and accessories store receives a delivery of designer merchandise from the bulging closets of well-dressed, well-heeled New Yorkers. Clever women head here for high-end European and American labels in tip-top condition – and at fabulous prices. It’s not uncommon to spot an Armani beaded evening jacket for $300 (regular retail $1500), an Hermes handbag for $900 ($2600) or a Michael Kors cashmere sweater for $250 ($1250). You’ll also find the occasional piece like a vintage Pucci dress.
