Kate Middleton's Trooping the Colour outfit had a deeper meaning. All about why the Princess of Wales wore aqua to King Charles' birthday parade on June 14.

The Duke, 40, and Duchess of Sussex, 43, last attended the military parade in 2022 for Queen Elizabeth’s Platinum Jubilee. Two years prior, they had stepped away from their royal duties and relocated to Montecito, California. Therefore, the couple had to watch the ceremony from a separate balcony alongside other non-working royals.
