Kate Middleton and Prince William attended the Cheltenham Festival in England today. The Duchess donned old favorites for this new outing — she accessorized with the same Lock & Co brown hat that she wore when she was a guest at a friend's Swiss Alps wedding with William and Prince Harry, and a tan coat that she has been sporting since 2007. The Cheltenham horse-racing festival is a favorite amongst royals and British socialites. William's cousin Zara Phillips and Kate's sister, Pippa Middleton, both watched the races this week ahead of Will and Kate's visit.
