A deep blue long-sleeve button-down covered in a tonal ripple pattern that shimmers with subtle texture under changing light. The all-over print creates visual depth without overwhelming, landing somewhere between a solid and a statement piece. The spread collar sits neatly and the slim silhouette follows the torso without pulling.

Cut from Italian cotton with a soft hand and natural stretch, this shirt resists wrinkling and holds its colour through repeated washes. The lightweight weave breathes easily, making it a reliable choice for office hours that run into evening plans.

Assembled from 26 individually cut pieces with German stitching, each seam is engineered to follow the body rather than fight it. Paris-designed and refined through an MIT-engineered fit algorithm built on data from 30 million men, the Eins line delivers a dress shirt that moves like a second skin.

Machine wash cold, hang to dry. Available in sizes S to 5XL.
