As temperatures climb, a tight circle of labels is quietly dictating what everyone from Hailey Bieber to downtown editors are actually wearing. These aren’t fleeting micro-trends; they’re the brands shaping how summer 2026 looks and feels on the street, on Instagram, and off-duty on the most photographed women in the world.

At the center of it all is Cou Cou, the British label that turned nostalgic pointelle lingerie into a full-blown wardrobe. Its Rina Tee, a softly clinging boatneck that’s been spotted on Hailey Bieber and Sabrina Carpenter, has become the season’s unofficial uniform. It’s the rare piece that reads polished with trousers and undone with cutoffs, and it’s fueling a renewed obsession with delicate, skin-skimming basics.

On the accessories front, Underwater Weaving is rewriting the basket-bag cliché. Designed by Erin and Peggy Pollard, each rattan piece is handwoven, meaning no two bags are exactly alike. The subtle variations in color and shape give them the kind of lived-in character that makes even a simple tank-and-shorts outfit feel considered.

Meanwhile, California mainstay Dôen continues its quiet reign. The brand’s gauzy dresses and blouses, all fluttering sleeves and smocked bodices, are the backbone of every romantic summer wardrobe. They move easily from farmers’ markets to weddings, which explains why they’re as beloved by stylists as they are by civilians.

Tank Air is responsible for the tank-top arms race. Its Studio Tank set the standard, but this summer the Half Moon Halter and Service Tank are the silhouettes to know, cut to frame the shoulders and collarbones with almost architectural precision. They’ve become the building blocks of minimalist, body-conscious dressing.

For those rebelling against beige minimalism, Spanish label La Veste is the antidote. Known for striped sailor pants and saturated color blocking, it leans into clashing hues and playful tailoring. The effect is joyful and a little irreverent, the fashion equivalent of a seaside carnival.

The Anteros is the insider’s answer to shirting. Its crisp button-downs and drawstring Coen Shorts, cut from sharp Italian cotton, offer a clean, almost editorial take on everyday separates, while Tom Ford’s archive-leaning sunglasses—especially the oversized Butterfly and Annabelle frames—anchor outfits with early-aughts glamour.

Rounding out the list is Emily Dawn Long, the New York label that still feels like a secret. Born from the designer’s own closet needs, the line’s slouchy, intuitive pieces embody the ultimate It-girl ideal: clothes that look like you barely tried, and somehow got it exactly right.
