Fibonacci Marthyr Watercolor Shirt

This long-sleeve dress shirt features vertical brushstroke stripes in rich blues, indigos, and hints of burgundy. The watercolor-style pattern gives each stripe an organic, hand-painted quality that shifts across the fabric. White buttons run down the front, and a spread collar frames the neckline cleanly.

Cut from a futuristic blended stretch fabric sourced from Italian mills, this shirt delivers four-way stretch, moisture wicking, and wrinkle resistance. Twenty-six individual pieces are assembled with German stitching and hand-finished in Turkey for lasting structure.

The Fibonacci long-sleeve silhouette is designed in Paris and shaped by Maceoo's MIT-engineered fit algorithm, calibrated using data from 30 million men. It pulls the shoulders back, improves posture, and carves a flattering V-shape through the waist.

Wash cold and lay flat to dry. Available in sizes S to 5XL.
