To call the dress the First Lady wore to the State Dinner for the British Prime Minister and his wife "floor length" would be an understatement. This deep blue, off-the-shoulder v-neck with ruching in the front is by New York designer Marchesa and has a train. The First Lady is as regal as ever for this gala event.
