Mrs. O was in San Francisco last night for a Democratic National Convention fundraiser, joined by Dr. Jill Biden and House Speaker Nancy Pelosi. For the appearance, Mrs. O wore a mauve leopard burnout dress from the Thakoon Fall Winter 2010 collection, which can be seen in greater detail here. Gorgeous!
Update: The first lady also wore Mary Esses earrings from the jewelry designer's Cage Collection, featuring oval green amethyst set in a nest made of wires and diamonds. Make that tres tres chic!
