Mischa Barton's Wet T-Shirt Contest

Former O.C. star Mischa Barton shows off her ruffled floral bra underneath her wet t-shirt as she grabs dinner at Beverly Hills eatery Mr. Chow on Monday.

Accompanied by pals Kim Kardashian and Carlos Lopez (also BFFs with Nicole Richie), Mischa hit up the Roxy nightclub where comedian Andy Dick performed.

P.S. Mischa, darling. Those boots are hideous.
