7 Diamonds Systematic Fit Short Sleeve Button Down in Navy Red — Size Medium // Preowned

7 Diamonds is a Los Angeles premium menswear label whose design philosophy centers on producing shirts that bridge the gap between elevated casual and polished professional dressing — garments built with performance construction and a modern, precise fit that moves with the wearer rather than restricting him. The Systematic Short Sleeve Button Down is a clean example of that approach: a woven button-down engineered around a Cotton-Spandex blend that delivers the refined surface character and visual polish of a premium casual shirt alongside the stretch and ease of movement that defines the 7 Diamonds construction identity. This shirt arrives preowned in good condition with no flaws.

The 97% Cotton, 3% Spandex construction is a highly considered specification for a premium casual button-down. The dominant Cotton majority delivers the natural breathability, refined surface texture, and polished hand-feel that a shirt designed for elevated casual and smart-casual contexts demands — the Spandex component adds just enough stretch to allow a clean, fitted silhouette to move freely without pulling or restricting through a full day of wear. The Navy with Red colorway is a sharp, high-contrast combination that carries naturally across a wide range of casual and elevated casual settings — Navy provides a grounded, versatile base while Red brings energy and personality to the palette without overwhelming it. The 7 Diamonds fit is the brand's signature modern cut: precise through the body with a clean, contemporary silhouette that reads as intentional and well-dressed in any room.
