A rich denim-blue wash with a soft, polished sheen gives this long-sleeve dress shirt the look of premium chambray elevated to dress-shirt status. The clean surface, dark tonal buttons, and a pointed spread collar keep the design refined and versatile. The fabric has a subtle luster that sets it apart from standard denim shirts.

Cut from a lightweight Italian-mill fabric with a smooth, satin-like hand, the Fibonacci is assembled from twenty-six precision-shaped pieces joined with German stitching. The construction delivers four-way stretch and breathability, making this an ideal crossover piece that moves from the office to evening plans without looking out of place.

Paris-designed and refined through an MIT-engineered fit algorithm calibrated on data from 30 million men, this shirt naturally pulls the shoulders back and tapers through the torso for a defined V-shape silhouette. It captures the West Coast spirit of relaxed sophistication, pairing easily with dark trousers or black jeans.

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