This long-sleeve Fibonacci dress shirt features a bold, psychedelic tie-dye pattern in deep blues, golden yellows, purples, and teal across the entire body. The vivid, organic splashes of color create a striking, one-of-a-kind appearance, while the pointed collar and tonal buttons maintain a refined finish.

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 ensure precision in every seam and 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 improves posture and flatters the body while allowing full freedom of movement.

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