However, royal fans noticed that little Louis' ensemble was the same that the Duke of Sussex wore for his second appearance at the Trooping the Colour event in 1986. In old photos, Harry is being held by Princess Anne and is seen wearing a white shirt with blue stitching and matching blue shorts, just like the ones Louis wore. Coincidently, both Princess Anne and the Duchess of Cambridge wore yellow.
The royals appear to have a tradition of having their children rewear their old baby clothes. Back in 2015 when George was 1 year old, he was dressed in the same baby blue outfit that his father, William, wore in 1984.
Louis has also previously been photographed sporting what appeared to be his big brother, George's, striped shorts, during a family outing last month.
