This long-sleeve Fibonacci dress shirt features a crisp white satin body with a large French bulldog portrait peeking over the chest area, accompanied by playful retro-style lettering. Dark accent buttons and a spread collar keep the whimsical design grounded in a polished dress shirt format.

Made from a blended satin fabric sourced from Italian mills, this shirt delivers four-way stretch, moisture-wicking performance, and wrinkle resistance. German-thread stitching and hand finishing in Turkey ensure precision construction that holds up through frequent wear.

Maceoo's Fibonacci line is Paris-designed and shaped by an MIT-engineered fit algorithm developed from data on 30 million men. Assembled from twenty-six individual fabric pieces, the shirt creates a natural V-shape through the torso that broadens the shoulders and improves posture while allowing full freedom of movement.

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