Prince Louisis all in on Throwback Thursday — in an outfit directly from his dad’s childhood.

Making hisTrooping the Colour carriage debut, the 4-year-old prince wore the same mini sailor suit that his father,Prince William, wore to Trooping at age 2 in 1985. (The same year Louis' uncle,Prince Harry, made his own Trooping the Colour debut!)

In 2019, Louis made his own balcony debut in another rewear — this one borrowed from Harry, who first wore the blue-and-white shirt with matching shorts back in 1986.
