The SEIJAKU Relaxed Long-Sleeve Shirt reinterprets the classic men’s shirt through a cleaner, more contemporary silhouette.
Cut with a relaxed, straight fit, it features a structured point collar, tonal button fastening and a fluid construction that allows the shirt to move naturally on the body. The minimalist front keeps the design refined, while the back yoke and double-button cuffs introduce subtle elements of traditional shirting.
The warm Camel tone gives SEIJAKU a sophisticated tonal character and makes it particularly versatile. Wear it open over a T-shirt for a more casual approach, buttoned as a shirt, or tucked into tailored trousers for a sharper silhouette.
Designed to sit between modern tailoring and elevated casualwear, SEIJAKU can be worn as part of a tonal set or contrasted with black, ecru and neutral separates.
