Mrs. Obama's best evening looks

Fashionistas were all over this red-and-black full-length gown by Sarah Burton of the British design house Alexander McQueen, which Mrs. Obama wore for the State Dinner with Chinese President Hu Jintao on Jan 19, 2011. The gown's color choice was widely considered a nod to China, where red symbolises good fortune and joy.
