All eyes were on Prince George at the christening of his little sister, Princess Charlotte, on Sunday. The toddler wore a white shirt and cherry red shorts for the occasion. The little boy looked out at the hundreds of spectators with curiosity, waved at them and even peered into his sister’s pram at one point.

George looked adorable and melted hearts as he waved to the crowds. Royal observers noticed something familiar about his appearance. He was once again wearing an almost identical outfit as his dad, Prince William, did 30 years ago. George’s outfit, however, is not a "re-wear." People confirmed that it is a new smocked set by Rachel Riley, a favorite children’s wear designer of his mom, Kate Middleton. The little royal completed his look with his favorite Start Rites Jo-style first walking shoes, without knee socks

“I’m absolutely thrilled and I think he looked so lovely. There is a trend for vintage-inspired pieces at the moment and it’s nice to see,” Riley noted. The designer added that choosing such timeless pieces shows a nod toward both the past and the future. She continued that the outfit is fashionable, and at the same time traditional. It will still be relevant even when he is crowned king. 

A blonde-haired William wore the same red shorts, white shirt and shoes combination as he visited his new brother Harry for the first time in September 1984. It’s the second time in recent weeks George has sported a retro ensemble. He wore a blue outfit identical to one his dad William wore at the same age for the Trooping the Color parade last month.

Princess Charlotte was christened in front of the Queen, Prince Philip and close family and friends. The rite, which brought the nine-week-old into the Anglican church, was watched by proud parents the Duke and Duchess of Cambridge and older brother George. Grandparents Prince of Wales and Duchess of Cornwall and Carole and Michael Middleton, and Kate’s siblings Pippa and James Middleton joined Charlotte’s five godparents for the celebratory occasion at St. Mary Magdalene Church in Norfolk.
