Hollywood came to Washington this weekend for the annual White House Correspondents' Dinner, bringing with them a glamorous collection of gowns. The style-conscious set — including Kate Mara, Claire Danes, Kerry Washington, and even Anna Wintour — hit the red carpet before heading inside for the Conan O'Brien-hosted festivities. Kate stepped out in a white Prada column gown. Claire, who also chose a Prada gown, arrived in a baby-blue-hued number, while Kerry opted for a black-and-white halter-style gown from Wes Gordon.
