Crisp white with paired neon-yellow and grey vertical stripes running the full length of the body, this long-sleeve dress shirt balances classic structure with a bold, modern color accent. Dark navy buttons contrast against the white ground, and a navy inner placket trim adds a hidden detail visible when the collar is open. The spread collar and clean barrel cuffs keep the construction polished.

Cut from a lightweight Italian-mill fabric, the Fibonacci is assembled from twenty-six precision-shaped pieces joined with German stitching. The weave offers four-way stretch and breathability, delivering comfort and structure that lasts from the first meeting of the day to a late dinner reservation.

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 brings a fresh burst of West Coast energy to any outfit, pairing naturally with navy chinos or dark jeans.

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