Kate Middleton bundled up in a furry coat, stayed casual in jeans, and kept her feet dry with green Wellington boots that matched those of her brother-in-law, Prince Harry, to watch her husband, Prince William, play a game of soccer on Christmas Eve. The boots, which William, Kate, and her sister, Pippa Middleton, have been spotted wearing previously for walks and hunting trips, are apparently made by Le Chameau — buy them here — and lined with leather. The Duke and Duchess of Cambridge were in Sandringham with the royal family for their first Christmas together as newlyweds. Kate and William attended Christmas services in the town, where they were greeted by a crowd of well-wishers on the holiday. 2011 has been an amazing year for Prince William and Kate Middleton, but the start of 2012 will have them apart for a couple of months as part of his military service.
