Another year, another Trooping the Colour ceremony, another look from Kate Middleton. Today (June 13), the Royal Family gathered at Horse Guards Parade in central London in celebration of King Charles III’s official birthday.

Each year for Trooping the Colour, Catherine, Princess of Wales has turned out a look that embraces summer’s prettiest color palette and features some kind of sentimental detail. 2026 is no different: Kate opted for an icy blue Catherine Walker Lafayette coatdress with white piped lapels, a nipped in waist, and strong shoulders, paired with a wide-brimmed, sculptural bow-topped Philip Treacy hat in a similar shade. (Both look like new purchases for the royal, who loves to shop her own wardrobe and frequently rewears her own pieces.) She styled the look with Cassandra Goad Cavolfiore pearl studd earrings, pointed white pumps, and an Irish Guards regimental brooch. (The latter a nod to her role as colonel.)

Catherine was joined for a sunny ride in the Ascot Landau carriage to the ceremony—as is tradition—by her children, Princes George and Louis, and Princess Charlotte. Her sons sweetly matched her look with their own pale blue ties, while Charlotte wore a puffy-sleeved, button front white tea dress and a matching bow in her hair. Prince William took part in the military parade in full uniform.
