There’s no question that the Princess of Wales feels most at home in nature – Kate Middleton’s signature look often includes skinny jeans and hiking boots. It’s no surprise then that for formal events, she usually chooses her go-to outfit of coat dresses and nude pumps – what you might call her “armor.”

The royal stuck to this reliable style once again at Tuesday afternoon’s Buckingham Palace garden party (May 20). She wore a yellow Emilia Wickstead midi dress – the same one she sported during Queen Elizabeth II’s Platinum Jubilee celebrations in 2022 – paired with a matching Philip Treacy hat she first wore to Prince Harry and Meghan Markle’s wedding in 2018.

Kate’s choice of butter yellow is particularly timely, as the sunny shade is trending this season, appearing on spring 2025 runways at Givenchy, Toteme, and 16Arlington. Given her longstanding connection with Givenchy’s new creative director Sarah Burton (who designed her wedding dress), could we see Kate wearing a custom Givenchy creation soon? We’ll have to wait and see.
