A constant on our Pinterest boards, Camille Cottin is the French star of Call My Agent! and House of Gucci. She mixes menswear with ease, keeps silhouettes relaxed and avoids anything that feels overdone. That balance is exactly why it works.

The piece that does more than it should.

If you add one thing this season, make it a slightly oversized, striped shirt with a menswear slant. It holds its shape, softens with wear, and works across the week without needing much from you. Here is how it earns its place.

There is a reason this shirt keeps resurfacing. It sits in that useful middle ground, structured but not rigid, relaxed but never sloppy. The stripe brings just enough interest without competing. The fit does the real work, slightly oversized, longer in the body, sleeves that push up and stay there.

Once you have the right one, the rest is adjustment.

Denim, but sharper

With relaxed or wide-leg jeans, it reads clean rather than casual. A slim tie, loosely knotted, adds a point of view without tipping into novelty.

Poolside, but intentional

Open over swimwear, it works as a cover-up with more presence. The stripe carries it. Slides by the water, then leather sandals and a structured bag, and it moves easily into the rest of the day.

Layered, not styled

Over a white vest or tank, left open and easy. Bermuda shorts or chinos keep it grounded. The proportions do the work, nothing needs forcing.

Tailoring, relaxed

Tucked into wide-leg trousers or left loose over a pencil skirt, it softens sharper pieces. A few buttons undone, sleeves pushed up. It keeps tailoring wearable through the day.
