Standing outside his new school, Eton College, in uniform for the first time on Tuesday, Prince George looked the spitting image of his father, Prince William, 31 years earlier.
Dressed in the iconic tailcoat, winged collars, and white tie, the 13-year-old future King's resemblance to his father on his first day in 1995 could not have been clearer.
Earlier in the morning, as William and Kate dropped off George for his big day, the father and son appeared to be wearing almost identical navy suits and suede shoes, with the only noticeable difference being spots on the latter's tie.

George has always had impeccable taste when it comes to picking outfits, and the Prince George effect, where every single item of clothing he wears sells out within minutes, has been in full swing for years now.
Some of his clothes have even been royal hand-me-downs from William's childhood – but sometimes they clearly just enjoy wearing a similar look.
See the other moments the pair have twinned over the years…
Euro finals - 2024

The pair, who are both passionate about the sport, looked on with the same tense expression and with their hands clasped.
They garnered extra twinning points for their coordinating outfits consisting of navy suits and striped ties.

Just like the arrival at Eton, they both wore navy suits over pale blue shirts.
But their matching sartorial choices also began much earlier…
Trooping the Colour - 2016

The little Prince wore the exact outfit of blue shorts and a white shirt with blue lining that the second-in-line to the throne wore in 1984 for his little brother Harry's christening.
A sweet snap of Harry's christening shows a young William running around during the family portrait to the amusement of his mum, Princess Diana, who was holding baby Harry in the photo.

While William wore long white socks and black shoes, Prince George was dressed for winter in all black and was allowed to snack on a candy cane for the church visit.
Trooping the Colour - 2015

Just like Prince William was carried by his dad, Charles, William held onto George as he showed him the flypast during the special occasion.
Princess Charlotte's christening - 2015

The youngster's Rachel Riley red-and-white outfit was very similar to Prince William's own look as a youngster, which he wore when he visited his baby brother, Prince Harry, in hospital for the very first time in 1984.

William and his eldest son were twinning it when they visited Kate and George's little sister, Princess Charlotte, for the very first time at the Lingo Wing of St Mary's Hospital in 2015. The father and son duo wore matching blue jumpers over white shirts, and the little Prince wore his staple pair of blue shorts.
Tour of Australia - 2014

The romper's style was clearly borrowed from Prince William's own very similar outfit from when he was a tot in photos with his mum, Princess Diana, at Kensington Palace.
