Some of my favorite looks from The Costume Institute's "Model As Muse" Gala:
Sasha Pivovarova in Giambattista Valli and Luigi Scialanga jewels, with Giambattista Valli.
Leighton Meester, in Louis Vuitton. Fun just like her character on Gossip Girl.
Daria Werbowy, in Balmain.
Erin O'Connor, in Jean Paul Gaultier and Solange Azagury-Partridge jewels.
