Mrs. Obama's best evening looks

She went for more of a flirter look with this sleeveless cocktail dress by Azzedine Alaia for a NATO summit dinner on April 3, 2009, in Baden-Baden, Germany. The black frock featured a ruffled skirt and was accessorized with matching patent pumps and simple jewlery.
