The First Lady has been chaperoning her husband on a trip to the UK, where she wore spring 2011 Marc Jacobs at an Irish pub and made time to chat with the royal family's newest member Kate Middleton. Critics have praised her fashionable egalitarianism, wearing a mix of both American and British designers. Critics were also unanimously entralled, as are we, by the white column-gown she wore to a formal banquet at Buckingham Palace (Cathy Horynsays: "The Ford number looks super on her -- flattering neckline, perfect fit, just right for all the pomp.") The dress was by Tom Ford, featured a criss-crossed bodice that exposed her oft-talked about shoulders and arms, had a bow detail at the waist, was the perfect shade of pearl and was worn with over-the-elbow gloves. While we sometimes find it a bit patronizing the way that the wives' of politicians are often compulsorily made into clothes horses, Michelle nailed it here, and we love that, as gay rights seem to be on the tips of the American-public's tongues, she subtly endorsed two of the most prominent gay designers in the U.S.
