Prince Louisis carrying on a royal tradition!

The youngest child of Kate Middleton andPrince William, who celebrated his first birthday in April, made hisBuckingham Palace balcony debuton Saturday at the Trooping the Colour celebrations. The young royal was wearing a white and blue outfit — and there’s a reason the ensemble looks so familiar: the clothes are hand-me-downs from his unclePrince Harry!

Harry, 34, wore the same outfit for his second appearance at Trooping the Colour back in 1986. In throwback photos, Harry looked adorable in the arms ofPrincess Anne, as she held the young prince up to greet the crowd, while many members of his family, including motherPrincess Diana, looked on.

Louis’ outfit was also reminiscent of the light blue outfit with cream lace that both his father and older brother Prince George wore at their first Trooping the Colour celebrations.

Trooping The Colour

At the time, she paired the accessory with an off-white Alexander McQueen coat dress (which itself was aroyal rewearfromPrincess Charlotte‘s 2015 christening and 2016 Trooping the Colour!) for the nuptials.

For his big debut, Louis joined his big brother George and big sister Charlotte along with the rest of the royal family.

Making his balcony entrance in the arms of his mom, the 1-year-old royal immediately began to wave excitedly to the crowds below, then reached for William who held him for the remainder of the iconic flypast.

Continuing to wave throughout the celebration, much to the delight of his mom, Louis even waved to his grandpa when the family turned to go back inside the palace.

Trooping The Colour

Louis celebrated his first birthday on April 23, which means he’s around the same age as Charlotte was during her first Trooping the Colour appearance.

George was a little older, nearly 2, when he made his Trooping the Colour debut in 2015, which is likely because at 10 months, he was too young for the exciting event the previous year.
