The Duchess of Cambridge is getting in the holiday spirit! On Tuesday, Dec. 4, Kate Middleton stepped out in a perfectly festive Christmas outfit to host a Christmas party for Royal Air Force (RAF) military families with her husband, Prince William at London’s Kensington Palace.

During the party, Kate addressed the attendees and thanked them for coming to the special event. “It’s really lovely to see you all here. Not only are we grateful for you coming here to join our party, but also for the sacrifices you make on a daily basis on behalf of the nation,” the 36-year-old said during her speech. “I can’t imagine how it feels when your loved ones are away on active service over Christmas or at those special family moments.” Scroll down to see pics of Kate’s Christmas outfit!
