Narciso Rodriguez, Jason Wu Behind This Week's Michelle Obama Outfits

On Sunday, she once again turned to Jason Wu for a violet raw silk sheath dress with embroidered knots as she welcomed students from the L'Academy de Cuisine to the White House kitchen. Later that evening, at the Governors' Dinner, Obama donned a sequined gown by Chicago native Peter Soronen. And at her husband's first address to Congress on Tuesday night, she turned to another one of her designer favorites, wearing a sleeveless plum silk dress by Narciso Rodriguez.
