And who designed their dresses? Why, the folks from the Gap!

Gap partnered with current and past CFDA/Vogue Fashion Fund winners Alexander Wang, Rodarte, Sophie Theallet and Thakoon to create original couture gowns for celebrity muses at this year's Costume Institute Gala Benefit, and Jessica Alba and Kirsten Dunst are two of the lucky ladies.

The theme of this year’s exhibition is American Woman: Fashioning a National Identity, and it will be on view May 5 through August 15. Who else was there?
