There’s no doubt that the Princess of Wales is most comfortable in nature: A Kate Middleton classic is a pair of skinny jeans and hiking boots. It makes sense, then, that for more formal engagements, she typically sticks to her uniform of coat dresses and nude pumps—her “armor”, if you will.

The royal returned to her tried-and-tested formula once again while attending a Buckingham Palace garden party on Tuesday afternoon (May 20). For the occasion, she opted for a yellow Emilia Wickstead midi dress, which she previously wore during Queen Elizabeth II’s Platinum Jubilee celebrations in 2022, along with a matching Philip Treacy hat, which she debuted at Prince Harry and Meghan Markle’s wedding back in 2018.

While Kate—known for her love of repeating past looks—has owned both pieces for several years, butter yellow also happens to be a strong contender for colour of the season, with the sunny shade being spotted on the spring 2025 catwalks at the likes of Givenchy, Toteme, and 16Arlington.

Given her long-time relationship with Givenchy’s newly installed creative director (and her wedding dress designer) Sarah Burton, could we see Kate Middleton wearing a custom creation by the French fashion house in the near future? Only time will tell.
