Princess Kate Dazzles in Princess Diana's Beloved Tiara

The Duchess of Cambridge stepped out in a tiara for a diplomatic reception.

The Duchess of Cambridge looked regal in red, recycling the same dress by designer Jenny Packham that she chose for her first state dinner with the Chinese President. She accessorized the look with diamond chandelier earrings.

Kate borrowed the Lotus Flower Tiara for her first State Banquet with the Chinese President and the Cartier Halo Tiara at her wedding.

The Queen wore her sapphire and diamond tiara and a dress by Angela Kelly. Camilla, the Duchess of Cornwall, dressed in a white, beaded, Bruce Oldfield gown with a Boucheron tiara, a pearl choker and diamond earrings.
