The First Ladies

Please note: This event has already occurred.
With more than two dozen gowns from the Smithsonian's almost 100-year old First Ladies Collection, this exhibition is a must-see, with dresses worn by Frances Cleveland, Jacqueline Kennedy and Laura Bush, as well as an examination of the role of presidential wives. If you've seen it, here's a reason to return: Michelle Obama's stunning one-shouldered Jason Wu gown from the 2009 inaugural is one of the most recent additions.
