The Many Matching Fashion Moments of Kate Middleton and Princess Charlotte

This past weekend, when Kate Middleton and Princess Charlotte attended Trooping the Colour—the annual celebration of the British sovereign’s birthday in London—they both did so wearing aquamarine. Their choice of such a distinctive blue was far from coincidental, or a rarity: the Princess of Wales and her 10-year-old daughter have long coordinated their outfits for their official appearances.

Take the coronation of King Charles, for which they both wore silver bullion and crystal flower crowns by Jess Collet and Alexander McQueen; or their Christmas day walks to church at Sandringham, where they frequently don the same festive hues. Although it’s not just the formal occasions where they embrace a matchy-matchy aesthetic: when the duo attended Wimbledon in 2024, Princess Charlotte had on a pair of purple sunglasses that corresponded perfectly with the hue of her mother’s Safiyaa dress. Sometimes, the coordination is obvious—like when both wore nautical-inspired looks to Trooping the Colour in 2024—while at other times it is more subtle, like when Charlotte’s coat matches her mother’s accessories (or vice versa.)

It doesn’t take a royal rocket scientist to figure out why: not only does a degree of color-coordination ensure a better looking photograph for the cameras (and remember, the monarchy is all about optics) but it symbolically suggests an innate connection between the wearers. Kate Middleton and Princess Charlotte are both kin and kindred spirits. An added bonus? Mother-daughter dressing can be, well, adorable. Who doesn’t smile when their child gets excited over looking like a mini-me? (Kylie Jenner and Stormi Webster, for example, often dress in complimentary outfits by the likes of Jean Paul Gaultier, Dior, and Marine Serre.)

Below, Vogue rounded up the royal duo’s best matching moments in the public eye—all the way back to Pippa Middleton’s wedding, where the then-Duchess of Cambridge wore a custom blush pink Alexander McQueen dress to match the bow on Charlotte’s flower girl frock.
