Kate Middleton dressed up in a floral Erdem outfit and matching hat for the wedding of her friends Thierry Kelaart and Patrick Heathcoat-Amory in Oxfordshire, England, on Saturday. She didn't have Prince William by her side, but Kate did have the company of her family. Her parents, Michael and Carole, were on hand, as was Pippa and her brother, James. Michael had an important role in the ceremony, since he walked the bride down the aisle. It was Kate's first appearance since returning to the UK from her recent Eastern tour with William. Kate and William wrapped up their travels less than two weeks ago, but William is already back to work as a helicopter pilot.
