Tonight was the State Dinner to honor French President Francois Hollande. The big news is the fact that he would come sans his partner of course--after the news of his "affair" (how French!). Well, that's old news, it's all about what the U.S. First Lady Michelle Obama wore. The first lady chose a dramatic Carolina Herrera ball gown with a voluminous skirt and lace applique top. Of note: the blue and black gown is the first dress with sleeves Obama has worn to a state dinner.
