For King Charles’ first parade as sovereign, the Wales children looked adorable in matching red, blue and white outfits, the colours of the Union Jack flag.
Whilst Prince George opted for a full navy suit, making him look very grown up, and a white shirt and red tie, Princess Charlotte chose a knee-length white dress with red details.
Prince Louis, five, on the other hand, looked adorable in red shorts, a navy-blue blazer, a white shirt and red tie, just like his eldest brother, and blue shoes which he wore with knee-high socks.

Royal fans, with a great eye for detail, were quick to point out that Prince Harry had worn an identical look back in 1989.
The youngest, who was almost five years old at the time, looked adorable as he accompanied his father, the then-Prince of Wales, and his brother Prince William, to the Beating Retreat military ceremony, which was held in the Orangery of Kensington Palace in London on the 29 June 1989.
For the special outing, Harry, who sported a bowl haircut, wore red shorts, a navy-blue blazer, a white and red striped shirt, a green and red tie and blue shoes and knee-high socks.
Although both looks are identical, there are clear differences between them, meaning that Louis didn’t borrow his uncle’s childhood clothes – this time!
