Hailey Bieber and Vittoria Ceretti define the anti-trend summer uniform

The new summer uniform is not a sundress, and it is not cutoffs either. Hailey Bieber and Vittoria Ceretti just showed the cleaner answer: denim with room, a sweatshirt or hoodie, and flip-flops, finished with wraparound sunglasses and a simple black shoulder bag. It reads less like a seasonal costume and more like a capsule piece you can actually repeat.

The anti-trend formula is built on restraint

On June 16, 2026, Who What Wear zeroed in on two Los Angeles sightings that looked almost deliberately unstudied. Bieber wore a sweatshirt with stovepipe jeans, flip-flops, wraparound sunglasses, and a simple black shoulder bag. Ceretti went one step slouchier in a gray zip-up hoodie, baggy jeans, a red T-shirt, flip-flops, wraparound sunglasses, and the same stripped-back bag formula. The point is not that the outfits were identical. The point is that both looks relied on the same quiet ingredients and let fit do the talking.

That is exactly why this feels newer than the old dress-or-shorts default. Dresses and shorts are obvious summer shorthand; this is more covered-up, more flexible, and a lot less eager to announce itself. The denim brings structure, the top keeps the look casual, and the footwear pulls the whole thing down to earth. Nothing is overstyled, and that is precisely the appeal.

Why this version of summer dressing feels current

Summer 2026 is moving away from the idea that warm weather has to mean maximum exposure or a closet full of one-note “outfit” pieces. Editorialist’s summer capsule guide, published June 10 and updated June 18, was built over months around versatility, which is the real signal here: people want clothes that mix without friction, not outfits that only work in one exact mood. The guide’s emphasis on tanks with tailored shorts, knits over swimwear, and dresses that can go up or down shows how much the season is leaning on adaptability.

But the Bieber and Ceretti formula has a different kind of power. It is less polished than a tailored short, less expected than a knit over swim, and more resistant to the “I tried too hard for summer” trap. That is why it feels so current. It nods to ease without collapsing into laziness, and it has the kind of off-duty discipline that makes celebrity dressing look wearable instead of aspirational in a dead-end way.

There is also a bigger editorial shift behind it. Editorialist’s summer trends coverage frames the season as a reset after seasons of uniform dressing, with more room for small, personal decisions instead of full-on maximal styling. That tracks with what is happening in the streets and in the feeds: the loudest style move right now is often the quietest one.

The capsule core: three staples, one repeatable silhouette

If you want the uniform to work in a real wardrobe, start with three pieces: a sweatshirt or zip-up hoodie, jeans with room through the leg, and a simple pair of flip-flops. That combination is the backbone of both looks, and it is the reason the outfit can move between errands, travel, and low-key appointments without needing a total rethink. The black shoulder bag and wraparound sunglasses are the finishers, not the foundation.

The denim matters more than people admit. Bieber’s stovepipe jeans keep the silhouette neat and slightly lifted, while Ceretti’s baggy jeans push it toward slouchier, more insouciant territory. Either way, the jeans act as a counterweight to the softness of the top. A hoodie alone can feel lazy; a hoodie with the right denim feels edited.

The footwear is the trickiest part, and also the most revealing. Flip-flops make the whole thing feel unmistakably summer, but they work because the rest of the outfit is so grounded. This is not beachwear pretending to be city dressing. It is city dressing that has loosened up enough to survive heat.

How to wear it beyond the sidewalk

The reason this formula earns real capsule value is that it can move across settings without losing its shape. For office days, keep the same denim-and-top pairing but make the footwear more polished, which is where the broader summer conversation around white sneakers becomes useful. A cleaner shoe instantly sharpens the look while preserving the easy silhouette that makes it feel modern.

For travel, this is close to ideal. A sweatshirt or hoodie handles planes and over-air-conditioned hotels, the denim gives you structure in photos and in transit, and the shoulder bag keeps the look practical without turning into baggage-handler chic. Who What Wear’s June archive is already orbiting this exact way of dressing, with coverage that includes white sneakers, an anti-denim pant trend, and even “The Ideal 10-Piece Summer Travel Wardrobe for 2026,” which tells you the audience wants formulas, not fantasy.

For dinner or late-day plans, the same logic still holds. The look only needs a small elevation, not a total rebuild. Swap in a better bag, keep the sunglasses sharp, and let the jeans stay relaxed. That is the whole charm of the anti-trend uniform: it is not trying to reinvent summer, just make it less obvious and a lot more repeatable.

The real shift

What Bieber and Ceretti are wearing is not anti-fashion. It is anti-dead-end fashion. The look skips the fragile logic of a one-off summer outfit and lands in the better territory of repeat wear, where every piece has a second and third life. In a season that is clearly favoring small personal edits over loud seasonal declarations, that is the uniform with the most staying power.
