We never doubted that Leighton Meester had the power to pull off almost any look, and as she breezed around New York promoting new movie The Roommate yesterday she showed she can go from girlie to sleek in the blink of an eye!
Appearing on Late Night With Jimmy Fallon the Gossip Girl worked an adorable flower-print mini matched with a pretty pink pout before hopping across town and changing into a chic layered shift by Giambattista Valli for a screening of The Roommate.
We love both looks on Leighton. What a style setter!
