Princess Charlotte and Prince Louis wear the same sneakers as family matches in blue for air show

Prince William and Kate Middleton surprised attendees at the Air Tattoo at RAF Fairford in England, accompanied by their children Prince George, Princess Charlotte, and Prince Louis. The royal family displayed a coordinated blue theme in their outfits, and the two younger children, Charlotte and Louis, took the matching theme to the next level.

Charlotte and Louis twinned in the same slip-on sneakers.

Charlotte, aged 8, and Louis, aged 5, sported navy canvas slip-on sneakers by Trotters, which have been a favorite choice for the royal children over the years. As they joined their parents and George, who will be turning 10 soon, at the world's largest military air show, Charlotte added a touch of femininity to her trainers with a white cardigan and a striped navy-and-white Rachel Riley dress with a Peter Pan collar, previously worn at last year's Commonwealth Games. Louis looked adorable in a navy sweater, matching shorts, and a white shirt underneath.

The Royal family went inside a C17 plane at the air show.

Prince George opted for a light blue Ralph Lauren polo shirt and green trousers, while Prince William wore a blue checked blazer and dress shirt. Both father and son coordinated their footwear, donning brown suede shoes for the family outing.

The coordination didn't stop at the shoes. William and Catherine matched their trousers, with both of them wearing navy pants and navy belts for the adventure-filled day. However, Catherine deviated from the blue theme with the rest of her outfit. She wore a new beige striped blazer by Blazé Milano, a white T-shirt, and navy suede flats from one of her favored brands, Emmy London.

Prince George looked noticeably taller as he stood next to his parents today.
