A long-sleeve dress shirt in deep black with a smooth, refined finish and tonal black engraved-logo buttons. The spread collar sits clean and structured, and the overall silhouette is streamlined and minimal, with no visible pattern or embellishment. The fabric carries a subtle sheen that reads polished under evening light.

Crafted from Italian mill stretch fabric, this shirt delivers four-way stretch, moisture wicking, and wrinkle-free performance. Twenty-six individually cut pieces are assembled with German stitching and hand-finished in Turkey, ensuring the shirt holds its shape from the first meeting to the last drink.

Designed in Paris and shaped by an MIT-engineered fit algorithm drawn from data on 30 million men, the Fibonacci Stretch sits close through the chest and shoulders, then tapers at the waist for a defined V-shape silhouette. It is the foundational black shirt, as comfortable under a blazer as it is worn open over a tee.

Wash cold and lay flat to dry. Available S to 4XL.
