Leighton Meester: You Know You Want It!

Leighton Meester and co-star Michelle Trachtenberg come out to support Gossip Girl‘s costume designer Eric Daman at New York’s legendary Fifth Avenue boutique, Henri Bendel, on Tuesday (January 12).

Daman‘s new book “You Know You Want It: Style-Inspiration-Confidence” is in stores now! You can pick up your own copy for just under $20 at Amazon.com.

FYI: Leighton paired her Louis Vuitton ensemble with a fierce pair of Balenciaga shoes. She also accessorized herself at the event with a little boyfriend material — Sebastian Stan! Michelle paired her navy Rag & Bone dress with Ippolita black onyx bangles and a Carla Amorim ring.
