Kate Middleton’s Blue Catherine Walker Look Steals the Show at King Charles’s Birthday Parade

Princess of Wales Kate Middleton drew attention at the annual official birthday celebration for King Charles III over the weekend, appearing with her children in a striking ice-blue coat dress by Catherine Walker. The royal event became a talking point on global fashion sites, with Middleton’s outfit standing out as the highlight of the day.

Her dress featured a white lapel, a narrow waist and strong shoulders. She paired it with a wide-brimmed matching hat by Philip Treacy, pearl earrings, white heels and an Irish Guards military brooch, a nod to her role as colonel. Prince William took part in the military parade in full uniform, in keeping with royal tradition.

Their children were also coordinated with the look. Princes George and Louis wore ties that matched their mother’s blue shade, while Princess Charlotte wore a white tea dress with puff sleeves and a matching bow in her hair.

The appearance continued Middleton’s pattern of carefully chosen royal outfits that mix summer colors with personal significance. The article notes that she attended the parade in 2024 after announcing cancer treatment, and that last year she and Charlotte wore matching aquamarine tones.
