On Saturday, the press decamped to Washington and brought celebrity friends with them in the annual awkwardness that is the White House Correspondents' dinner! Michelle Trachtenberg, Scarlett Johansson, Brooklyn Decker, and Salma Hayek were a few of the ladies in attendance at the various soirees associated with the evening. And they wore evening dresses, which are always fun to look at. It's no Met Ball fashion, but to tide you over until that starts, enjoy the aforementioned ladies and more in their fancy Washington outfits in the slideshow.
