For last night's Vanity Fair and Juicy Couture Vanities Calendar party in West Hollywood, the styles proved fun and flirty, and they certainly favored leg-baring numbers. Olivia Munn, who also shared hostessing duties, stepped out in a navy-and-white tuxedo-inspired minidress by Bird, and paired the look with a Juicy Couture clutch and peep-toe pumps. Meanwhile, bold prints took center stage thanks to Jaime King's Alexander McQueen dress and Brooklyn Decker's matching top and skirt set from Preen's Spring '13 collection. Eva Longoria opted not to walk the red carpet — and worked a casual outfit inside — while Kate Mara, Ellie Kemper, and Minka Kelly turned out even more cool cocktail ensembles. See it all inside, then vote on your favorite look at the end of the slideshow!
