Prince George wore the same outfit to the Queen's official birthday celebration as his father William wore nearly 32 years ago to Prince Harry's christening in 1984.
The short sleeved white shirt with peter pan collar, edged in a blue trim around the collar and cuffs, and blue shorts will have been preserved by those who care for the royal wardrobes.
The last time George appeared on the balcony he also wore one of the Duke's childhood outfits - a pale blue romper suit which William appeared in after Trooping the Colour as a toddler.

The prince was allowed to stay up past his bedtime to meet the US president.
The pictures were taken after President Obama and the First Lady had dinner at Kensington Palace with the Duke and Duchess and Prince Harry, as part of their four-day UK visit.

David Cameron has said the Duke and Duchess of Cambridge deserve "some privacy and some space" to bring up their children.
Kensington Palace has accused paparazzi photographers of harassing Prince George to gain lucrative photographs.
I am concerned and I have every sympathy with the royal couple. They very generously have made available pictures of their wonderful children to the British press and the British press have behaved, frankly, very well because they printed those pictures. But they haven't been, as I understand it, printing paparazzi pictures and it's very important they don't because if you start printing the paparazzi pictures, the paparazzi go further and further in trying to get pictures of the royal family.
What we need to do now is to persuade some of these foreign publications not to use these pictures. I do think William and Kate deserve some privacy and some space as they bring up their children. They do make available some pictures so we can all see and share in the joy they've got with their children but they should not be harassed by paparazzi.
