Theory’s summer 2025 collection draws focus to lightweight knits, putting breathability at the center of warm-weather dressing. The cotton-linen Brenan polo leads the way, its open weave and soft collar made for sunlit afternoons. Styled with tailored pants, the polo feels equally suited to city errands or a quiet moment on a shaded patio.

Next, the Kolben tee continues Theory’s exploration of texture, cut from a cotton-linen blend that brings clarity to a simple silhouette. Worn with dark, relaxed trousers and white sneakers, the tee lands in that space between sportswear and daywear.
Theory’s camp collar shirt introduces a fresh take on resort style, shaped with a boxy fit and soft cotton that skims the body. This shirt moves from an open collar and shorts at midday to casual layering for the evening, holding its own in both settings.
To round out the edit, Theory’s striped cotton-linen tee delivers a touch of pattern, with black stripes running through natural fiber. This tee pairs with relaxed trousers for a look that feels rooted in vintage sportswear, yet remains grounded in the present.
