The Fibonacci Marthyr Blue is a long-sleeve dress shirt with a bold, abstract print in navy, teal, white, and coral arranged in a distressed, textured grid pattern. The effect is artistic and eye-catching without being overwhelming. A pointed collar frames the neckline, while tonal dark buttons blend into the print for a seamless finish.

Built from Italian mill fabric, the shirt delivers the comfort and drape that comes with precision construction. Twenty-six individually cut fabric pieces are assembled with German stitching and hand-finished in Turkey.

The Fibonacci fit follows Maceoo's MIT-engineered algorithm, designed in Paris to pull the shoulders back and create a natural V-shape. For men who want a shirt that starts conversations without saying a word.

Wash cold and lay flat to dry.
