Kate Middleton and Princess Charlotte Opt for Aquamarine for Trooping the Colour 2025

Trooping the Colour is the annual official celebration of the reigning monarch’s birthday; it’s a joyful occasion, featuring the Royal families in a mode of celebration—and if you’re Prince Louis, with a bit of cheekiness and carry on—with outfits to match, to see and be seen. Kate Middleton has long made it the time to debut her most striking, spirited looks.

Crowds gathered in their thousands to watch the parades in central London that continued down the Mall toward Buckingham Palace, seeing members of the Royal family arrive in their house-drawn carriages. Catherine, Princess of Wales, husband Princess William, and their children George, Charlotte, and Louis were among them.

The Princess wore a bright aquamarine woollen dress coat with ivory lapels and cuffs by Catherine Walker—a designer favored by Kate Middleton as much as Princess Diana—as well as wide-brimmed matching hat with a sculptural motif by Juliette Botterill. Jewelry is always a key and sentimental part of the Royal’s looks, and today was no different: She opted for an Irish Guards Regimental Brooch—a nod to her role as colonel—and earrings that belonged to the late Queen Elizabeth.

Princess Charlotte followed suited in a dress that was a similar shade to her mother’s, with a white waist bow and white flats, her long hair tied in a braid.
