There is a certain kind of confidence that doesn’t need to be loud. COS understands it instinctively. For Summer 2026, the brand approaches swimwear with the same precision that defines its entire universe – controlled, architectural, and quietly striking. Nothing feels overworked. Nothing tries too hard. And yet, everything lands exactly where it should.This is not swimwear designed for the beach alone.
It is swimwear designed for a state of mind.

Less Skin, More Attitude

The silhouettes are sharp, almost sculptural. A one-shoulder swimsuit that feels more like a piece of modern design than a seasonal trend. Tailored swim shorts that blur the line between city dressing and coastal ease. Pieces that move effortlessly from rooftop to ater, from sun to shade.There is a clarity to the cuts – clean lines, uninterrupted shapes, proportions that feel instinctively right. The body is not overexposed, but framed.

Defined without being restricted.The palette remains disciplined. Deep blacks, softened neutrals, tones that absorb light rather than compete with it. It is not about color. It is about presence.What makes the collection resonate is its restraint. In a moment where swimwear often leans toward excess, COS does the opposite. It reduces. It sharpens. It refines.And in doing so, it becomes undeniably modern.The materials follow the same logic – technical, smooth, almost second-skin. There is structure, but it never feels rigid. Movement is effortless. Comfort is assumed.

Every detail is considered, yet invisible.
