The annual Veuve Clicquot Polo Classic is a prime spot for the chicest kind of celebrity style sightings. This year's event drew a crowd of Hollywood favorites and fashion insiders who brought their Summer dresses, sandals, and even a little denim on denim to the event at Liberty State Park over the weekend. Dree Hemingway kept it easy in a chambray jumpsuit, which she finished off with a touch of the '70s: round shades and platforms. Camila Alves took a sexier approach in a sunny body-con dress, complete with nude peep-toe pumps and aviators. Meanwhile, Ashley Olsen showed off her unique sense of style in a bright embroidered caftan and flats, and Rosario Dawson worked a breezy, seasonal LBD with gold jewels and printed platforms. Take in all the looks below, then tell us: who stole the show at this weekend's polo match?
