I like Misha Barton, but my favorite alum from ‘The O.C.’ is definitely Rachel Bilson. If you haven’t seen her in Zack Braff’s ‘The Last Kiss’ you should do so. Immediately. The girl is a special kind of sexy. Here at the Antibes, Chanel, Fashion Show, Rachel proves you don’t have to be dressed in something low cut or skin tight to be sexy. She has a sort of classic, exotic beauty that is definitely appealing even when the only real skin she’s showing is her legs. And come on – those are some gorgeous legs. Rachel always plays to her strengths and this relatively demure ensemble is no exception. Love her.
