Out for yet another high-profile public appearance, Prince William, Duke of Cambridge, and Catherine
, Duchess of Cambridge, attended the Order of the Garter Service at St George's Chapel in Windsor, England on Monday (June 13).

Looking elegant in a silver suit with a matching fascinator, Miss Middleton stood alongside the Duchess of Cornwall as the ladies watched on while Prince William and Prince Philip partook in the royal ceremony held at Windsor Castle.

During the festivities, Lord Phillips of Worth Matravers and Admiral Lord Boyce were invested in the castle’s Garter Throne Room before being "installed” at the service.

For those unfamiliar with the UK happenings, 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.
