During his first Trooping the Colour parade on Saturday, the one-year-old waved to the public wearing a vintage hand-me-down from his uncle.
The white shirt with blue embroidery and bright blue shorts combo was first seen on Prince Harry in 1986.

At the age of two during that year, Prince Harry posed with Princess Anne during the annual Trooping the Colour ceremony.
Both toddlers were held on the balcony of Buckingham Palace.
Not only this, but some reports have also pointed out how similar the Duchess of Cambridge and Princess Anne also looked with their hats and yellow-toned dresses.
And this is not the first time hand-me-downs were seen in the royal family.
In 2015, Prince George (also during the Trooping the Colour parade) wore the same outfit his father Prince William wore in 1984.

The powder blue peter pan collar shirt and matching shorts were also worn by the Duke of Cambridge during Prince Harry’s christening. The two just wore difference shoes.
