Chiropractors can thank Leighton Meester for a sharp uptick in business this week. On Tuesday night in New York, the "Gossip Girl" starlet triggered a whole lot of neck-snapping double takes when she hit the Harry Winston Court of Jewels event sporting a see-through lace Marchesa jumpsuit.

From the front, her sheer couture had a sort of "1001 Sexy Arabian Nights" vibe, thanks to harem pants and a dangerously plunging neckline. Then she turned around. Click through the photos at left to see how Leighton provided a full and shapely moon for those 1001 nights.

Meester has never shied away from taking red-carpet risks, even when she probably should. And it's gotta be tough starring opposite Blake Lively, what with her being Vogue overlord Anna Wintour's personal favorite and all. But does Leighton need to resort to displaying her derriere? Vote and then tell us what you think in the comments!
