The Eins Marthyr Black is a long-sleeve dress shirt in deep charcoal with a tone-on-tone geometric jacquard pattern woven into the fabric. The angular, faceted design catches the light at different angles, adding depth and texture to what reads as a dark, understated shirt. A lime green accent piping runs along the inner placket for a hidden flash of color, while dark tonal buttons keep the front clean.

Built from Italian mill fabric with twenty-six individually cut pieces, German stitching, and hand-finished construction in Turkey. A patterned contrast inner placket adds another layer of design detail visible only when unbuttoned.

Maceoo's Paris-designed, MIT-engineered fit algorithm pulls the shoulders back into a confident V-shape, improving posture and creating a silhouette that flatters naturally. A shirt for men who appreciate subtlety with an edge.

Wash cold and lay flat to dry.
