Ksenia Bradner in Jason Wu Spring 2012

Ksenia Bradner and Karlie Kloss were Jason Wu's arm candy at the Cartier Juste un Clou after-party at Skylight Studios in New York City.

Whilst Ms. Kloss wore Cushnie et Ochs, Ksenia of course wore Jason Wu.

Her gorgeous peplum feather trimmed dress is from the Spring 2012 collection.

As always, Ksenia added bright accessories to punch up her look: Christian Louboutun blue glitter peep toes, Ethne sapphire earrings, and a Judith Leiber minaudiere.
