Not one to shy away from avant-garde pieces, the "Gossip Girl" starlet wore a Marchesa jumpsuit from the designer's Spring 2011 collection while attending the Harry Winston Court of Jewels recreation launch in New York City.
The jumpsuit, which featured sheer black lace, an aggressively plunging neckline, and an open back, left very little to the imagination.
Possibly as a form of rebellion from their über-preppy alter egos, the "Gossip Girl" ladies have recently been seen sporting the black lace trend in some scandalous styles.
Blake Lively wore this Elie Saab backless, black lace frock in October while Taylor Momsen sported thigh-high lace stockings in August.
Meester completed her lace look with a funky ball purse, black Nicholas Kirkwood heels, loosely pinned waves, and bold red lips.
