All eyes were focused on Prince George, Princess Charlotte and Prince Louis.

On June 2, the siblings—children of Prince William and Kate Middleton—arrived together alongside their mother Camilla, Duchess of Cornwall in a horse-drawn carriage in the procession of the Trooping the Color parade, which kicks off four days of festivities for Queen Elizabeth II‘s Platinum Jubilee.

Charlotte, 7, wore a light blue dress with sheer sleeves, while her older brother George, 8, donned a navy suit, white collared shirt blue tie. Their younger broTher Louis, 4, sat in between his siblings, rocking a blue and white sailor-inspired ensemble to the celebration—similar to an outfit his dad William wore years prior—which marked their grandmother’s 70th year on the throne.

As they marched through the parade, the trio waved to the people. As they were saluted, the siblings took a moment of silence to bow. The children were seen looking out of the Major General’s Office window, overlooking the parade grounds, after the procession.
