Kate Middleton Has Quietly Perfected the Summer Capsule Wardrobe

It was the oversize Wimbledon look viewed ‘round the world. When the Princess of Wales stepped out for day four of the annual London-based tennis tournament, she was wearing a Gabriela Hearst linen double-breasted blazer and straight-leg pants. It’s a summer-friendly suiting option that looked beautiful paired together, though each piece is elegant enough to stand on its own. (That blazer would look lovely paired over a dress while the pants would be gorgeous with a white button-up or blouse.) In fact, many a royal (or royally adjacent figure) has stepped out in blue linen this season. Carole Middleton, Queen Mary of Denmark—they’ve each donned a similar blazer style this season. Now, it’s top of our list for our own summer wardrobe.

During a visit to Evelina Children’s Hospital, Princess Catherine reached for a royal repeat—a little white dress from Suzannah London, but one with loads of movement, too. (The brand even shared a deep dive on their Instagram page about the crepe style, known as the Flippy Wiggle dress.) Kate made the look her own, trading the thin white belt for one in black, but her decision to repeat this style for summer speaks to the versatility (and effortlessness) of a little white dress in your closet.

When Kate traveled to Reggio Emilia in Italy—her first solo international tour since her cancer diagnosis—in June, she leaned on lightweight and packable pieces: this pleated skirt from Jenni Kayne included. The neutral style was something she could easily pair with a white tank and earth-toned blazer. But the midi length and swishy material (which gives movement, much like her Suzannah London dress) have an easy-breezy quality that adds plenty of visual interest, too.

Lemon—or canary—yellow has decidedly replaced butter yellow as the “it” color for summer 2026. Cut to the Princess of Wales at Royal Ascot this season, dressed in a Roksanda style (another repeat) that made her impossible to miss in the crowds. It certainly makes the case for choosing a bold and eye-catching hue. The unofficial term for it is dopamine dressing—when you choose clothing that actively triggers a mood boost—but it’s certainly a key way to think about building out your own royal-inspired capsule wardrobe. (In other words, core pieces you can mix and match are great, but don’t shy away from a one-and-done look that’s a total standout.)

It was a surprise appearance by Princess Catherine at the Royal Charity Polo Cup and she was dressed in one of summer’s most hard-working prints: gingham. Her Temperley London dress (which is past-season) felt easy breezy. It was also an instant reminder that this is a pattern, in any color, feels both timeless and playful. Especially great? It’s a look that requires very little styling. (In the case of the Princess of Wales, she paired it with a bracelet stack and sunglasses—that’s it.) Another staple worth adding to your summer capsule, not to mention one you’ll reach for again and again.
