A long-sleeve button-down shirt in a solid dark navy with a clean, smooth finish. Light blue engraved buttons provide a subtle contrast, and the cuffs reveal a printed blue stripe lining when folded back. A matching inner placket and collar trim add hidden detail. The pointed collar and tailored body keep the profile sharp.

Cut from Italian stretch fabric with four-way give, this shirt is wrinkle-resistant, moisture-wicking, and breathable. Twenty-six individual pieces are joined with German stitching for enduring construction.

Conceived in Paris and built around an MIT-engineered fit algorithm developed from 30 million body scans, this Eins shirt enhances posture and creates a V-shape silhouette. It is a polished essential that transitions from office to evening with West Coast ease.

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