This long-sleeve Fibonacci dress shirt features a solid black satin body with a bold, colorful geometric skull graphic rendered in stained-glass-style prism colors across the lower chest. Orange accent buttonholes and the pointed collar keep the finish sharp against the dark base.

Crafted from a moisture-wicking, four-way stretch satin fabric sourced from Italian mills, this shirt resists wrinkles and dries quickly. German stitching and hand-finished construction in Turkey ensure precision in every detail.

The Fibonacci line is Paris-designed and built on an MIT-engineered fit algorithm calibrated from data on 30 million men. Twenty-six individual fabric pieces create a V-shape silhouette that pulls the shoulders back and improves posture while keeping you comfortable.

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