The Duchess of Cambridge's collarless Christmas coatdress was reportedly created for her by an "independent British designer". We're big fans of the kind of totally cool Jane Corbett hat that Kate chose. Kate's suede pumps were reportedly custom made by Mascaró at the request of the Duchess.
Kate's amethyst earrings, thought to be a Christmas gift from Prince William, are by fave Kiki Mcdonough. A similar pair can be seen above.
