White House Correspondents' Dinner

Tonight marks the annual White House Correspondents' Association Dinner at the Washington Hilton Hotel, hosted by Conan O'Brian. For the formal event, dubbed the "nerd prom" by the media set, Mrs. O chose a black beaded, draped chiffon goddess gown with high neckline in Chantilly lace by designer Monique Lhuillier.

More to follow and happy weekend!

Update: Mrs. O wore earrings from New York-based jewelry designer Catherine Angiel, confirmed by the designer on Twitter here.
