When the Obamas departed Washington early Tuesday morning, Michelle was outfitted in a white Thakoon coat, black dress, and black heels, looking a little bit like Jackie Kennedy upon her trip to France in 1961.

But somewhere along the way she managed a mid-air makeover, and stepped off the plane at London's Stansted Airport in full cocktail attire: a mustard yellow Jason Wu (according to WWD) dress with a long black evening coat, cinched at the waist with her favorite Azzedine Alaia belt.

What do you think the Obamas did to pass the six-hour flight? Did they talk on the phone to their daughters? Watch movies? Eat cheeseburgers? Share your ideas below.
