This long-sleeve Fibonacci dress shirt is rendered in a deep, solid black with a subtle satin finish that gives the fabric a refined sheen. A wide spread collar with a textured panel detail frames the neckline, and tonal black engraved-logo buttons run the length of the front placket, maintaining a sleek, monochromatic appearance from collar to cuff.

The shirt is constructed from a satin-finish blended fabric sourced from Italian mills, delivering a smooth surface with a gentle drape. This fabric holds its shape throughout the day while offering four-way stretch and moisture-wicking performance for all-day comfort.

Maceoo's Paris-designed Fibonacci cut is engineered using a proprietary MIT algorithm drawn from data on 30 million men. Twenty-six precision-cut pieces are stitched with German thread and hand-finished in Turkey, creating a fit that gently corrects posture and produces a natural V-shape silhouette.

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