Soft chambray blue with a subtle crosshatch texture, this long-sleeve dress shirt keeps its visual impact quiet and versatile. The real personality comes from the contrast details: a black inner collar and cuffs printed with a colorful butterfly motif that flashes when the sleeves are rolled. Light blue buttons down the front match the fabric tone for a seamless, cohesive look.

Cut from a lightweight Italian-mill fabric with a natural, linen-like hand, the Eins is assembled from twenty-six individually shaped pieces joined with precision German stitching. The construction delivers four-way stretch and breathability, making this an ideal warm-weather dress shirt that still holds its tailored line.

Designed in Paris and refined through an MIT-engineered fit algorithm calibrated on data from 30 million men, this shirt draws the shoulders back and sculpts a clean V-shape through the torso. It pairs equally well with dark trousers for the office or rolled-cuff jeans for a relaxed West Coast weekend.

Wash cold and lay flat to dry. Available S to 3XL.
