The Duchess of Cambridge joined her husband, Prince William, and other members of the royal family for the annual Garter Day service at St George's Chapel in Windsor, and she looked gorgeous, as per usual, in a bright red ensemble. For the occasion, Kate shopped from her own closet, choosing a Catherine Walker coatdress in a cherry hue. She previously wore this piece while touring the United States and Canada in 2011. The Duchess accessorized the bold look with coordinating accessories, teaming the tailored ensemble with red suede pumps, a small clutch, and a bright fascinator. She styled her long brown hair in a sophisticated low chignon. Meanwhile, Prince William eschewed civilian clothes, instead opting to don the traditional uniform that reflects the history of the event. "The Order of the Garter is the oldest and most senior Order of Chivalry in Britain, established by King Edward III nearly 700 years ago," Kensington Palace wrote alongside an Instagram from the event. "The Duke became the 1000th Knight in the Register in 2008."
