WHAT SHE WOREMeester
vamped it up at the premiere of The Roommate
in a leather-topped Michael Kors
cutout gown, Harry Winston
diamond studs and Brian Atwood
WHY WE LOVE IT
This is a sultry upgrade from Blair Waldorf's prim style! Sleek strands and smoky eyes added extra va-va-va-voom to Meester's smoldering look.
