A long-sleeve button-down shirt in a dark navy-black with a tonal patchwork pattern blending geometric, maze, and hexagonal motifs across the fabric. The design is subtle and reveals itself as light plays across the surface. Lilac-toned buttons add a distinctive accent against the dark base.

Cut from Italian fabric with four-way stretch, this shirt is wrinkle-resistant and breathable. Twenty-six individual pieces are joined with German stitching for a construction built to endure.

Designed in Paris and precision-fitted using an MIT algorithm drawn from 30 million body measurements, this Fibonacci shirt enhances posture and creates a flattering V-shape. It is a sophisticated evening shirt that balances complexity and restraint.

Machine wash cold, hang dry. Available in sizes S to 5XL.
