See Barton stage her own show (one day, four outfits!) at Fashion Week. Plus: Rachel Bilson, Christina Aguilera, George Clooney and more

STYLE CHAMELEON

Mischa Barton is one busy lady, making several fashionable appearances while jet-setting around New York's Fashion Week on Wednesday. The actress (from left) showed off her floral instincts at a Saks Fifth Avenue bash, went a bit dotty at the Mischon Schur show and ended the night with a frill to check out Anna Sui's runway collection.
