Kate Middleton and the British royal family gathered in Windsor today to celebrate the Order of the Garter, for an event called Garter Day. The Princess of Wales, though not a member of the Order, was in attendance in Windsor today to watch the procession. King Charles, Queen Camilla, Prince William, Prince Edward, Princess Anne, and the Duke and Duchess of Gloucester are all members of the Order of the Garter, the “oldest and most senior Order of Chivalry in Britain,” which was established by King Edward III almost 700 years ago.

The Princess of Wales and the Duchess of Edinburgh smile as they attend the 2026 Order Of The Garter Service.

For the occasion, she wore a custom Patrick McDowell dress and accessorized with a matching wide-brimmed Jane Taylor hat. Per the brand, “The fabric has been specifically woven for Her Royal Highness by Stephen Walters & Sons, in Suffolk.” McDowell said, “It has been a wonderful collaboration, developing one of my existing pieces with Stephen Walters, for Her Royal Highness.”

Kate watched the procession alongside Sophie, Duchess of Edinburgh, who also is not a member of the Order but a regular attendee on the festive day. Kate also chose her custom Robinson Pelham wedding earrings, a gift from her parents Carole and Michael Middleton. An official press release from the royal wedding described the pair as a “diamond-set stylized oak leaves with a pear shaped diamond set drop and a pave set diamond acorn suspended in the center.” The oak leaves and acorns are both symbols used in the Middletons’ coat of arms, which was granted to them before the wedding.

Today marks the Princess of Wales’s tenth time attending Garter Day; she first was at the event way back in 2008, before she was even a member of the royal family. That year, Queen Elizabeth appointed Prince William to the Order of the Garter, and William became the 1,000th Knight in the Register—a notable honor. Her fashion has remained consistent over the years, favoring dresses and matching hats, though in recent appearances she has favored longer hemlines versus the knee-length outfits she wore in her earlier years as a royal.
