Kate Middleton Gives The Butter Yellow Trend An Elegant Upgrade At Garter Day 2026

Butter yellow was one of 2024's biggest trends, and it's about to become huge again this summer, particularly as Kate Middleton rocked the shade at Garter Day on June 15th. While other members of the royal family, such as King Charles III and Prince William, were dressed in elaborate robes and feathered hats, the Princess of Wales celebrated the Order of the Garter at Windsor Castle in a gorgeous soft yellow coat dress in a jacquard material that instantly elevated her 'fit. One of the royally strict fashion rules Kate rarely breaks is staying away from dark colors, so the butter yellow hue made with the rich fabric was the perfect choice for this time-honored event.

Kate's 2026 Garter Day 'fit was made with the princess' tastes in mind. As reported by Town & Country, the native British designer Patrick McDowell stated, "The fabric has been specifically woven for Her Royal Highness by Stephen Walters & Sons, in Suffolk." He added, "It has been a wonderful collaboration, developing one of my existing pieces with Stephen Walters, for Her Royal Highness." The coatdress is one Kate Middleton outfit that meant more than you ever knew, as according to McDowell's website, he's all about sustainable fashion and using climate-friendly fabrics. As we all know, Kate is all about the environment, and the many pieces she's re-worn show just how crafty she is at recycling outfits.

There's a reason Kate Middleton's aesthetic is so classic, and that's why she never looks dated in any of her pics. The royal often chooses structured jackets and flowy skirts that can be paired with anything and reworn as-is, which is what she did at the 2025 Order of the Garter ceremony. Kate's outfit, which she had repeated like a sustainable fashion queen from 2021, featured a white boucle belted jacket, and a silky pleated skirt with a lace hem. With her wide-brimmed hat and layered pearl necklace, the University of St. Andrews grad was the epitome of timeless elegance.

It's clear that Kate is sending the message that sustainable dressing is possible by choosing elevated pieces in carefully crafted fabrics that stand the test of time. It also helps that a lot of her items are bespoke, which means she can tailor them according to her preferences. "When she chooses something custom-made, it's often in a neutral shade — usually something like blue or navy — which makes it much easier to re-wear in different ways over time. These types of pieces are always created with longevity in mind," stylist Susie Hasler shared with Hello!. She added, "Custom garments also tend to be more classic rather than trend-driven, which means she can repeat outfits for years without them feeling dated." So that's the secret to Kate's enduring style over the years!
