Duchess Kate sparkles in Erdem at Buckingham Palace reception

This Princess has the sparkle factor down pat.

The Duke and Duchess of Cambridge, Prince William and Kate Middleton, joined the Queen and Duke of Edinburgh for a reception at Buckingham Palace on Monday. Wearing a shimmering dress by Erdem and equally sparkly pumps, the Duchess turned heads as she walked into the event. Her shoes are the Oscar de la Renta Platinum Lamé Cabrina pumps, and retail for a cool $690. Kate rounded out her look with a pair of pearl drop earrings by Indian designer Anita Dongre, giving a nod to the reason for the celebration.
