A long-sleeve button-down shirt in a deep navy with a subtle tonal diagonal texture across the fabric. The pattern is visible only as light shifts across the surface, giving the shirt a sophisticated, understated depth. Tonal dark buttons and a pointed collar complete the sleek profile.

Cut from Italian stretch fabric with four-way give, this shirt is wrinkle-resistant, moisture-wicking, and breathable. Twenty-six fabric pieces are assembled with German stitching for a precise, long-lasting construction.

Designed in Paris and precision-fitted using an MIT algorithm built from 30 million body measurements, this Eins shirt enhances posture and creates a V-shape silhouette. It is a refined, versatile foundation piece for West Coast evenings and beyond.

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