Prince William & Kate Middleton: Order of the Garter Service

They've had quite the stretch of public appearances as of late, and Prince William and Kate Middleton were back at it while joining in on festivities at the Windsor Castle in Windsor, England on Monday (June 18).

Looking angelic in a white Alexander McQueen coat dress with a Jane Corbett hat, the Duchess of Cambridge and her royal husband took to St George's Chapel for the annual Order of the Garter Service.

Also in attendance at the lavish ceremony were Queen Elizabeth II and her husband, Prince Philip, along with Camilla, Duchess of Cornwall, and Sophie, Countess of Wessex.

The Order of the Garter is the senior and oldest British Order of Chivalry, founded by Edward III in 1348. Membership in the order is limited to the sovereign, the Prince of Wales, and no more than twenty-four members.
