Mathieu Castanier is an internationally recognized master tailor and fashion designer who blends the traditional craftsmanship of Savile Row with modern technology and innovation. Specializing in bespoke clothing and shoes including suits and leather jackets he serves a discerning, high-end clientele worldwide.

Beginnings on Savile Row

His journey began on London’s legendary “Golden Mile of Tailoring”, where master cutters instilled the fundamentals of British bespoke: structure, balance, and precision. From pattern drafting to hand-finishing, he learned that a bespoke suit is more than clothing it is a symbol of status and timeless refinement.

The Neapolitan School

Further experience with Italian sartoria added lightness, freedom, and natural elegance. Details like spalla camicia shoulders, high armholes, barchetta breast pockets, and softly structured jackets bring ease and movement proving that bespoke can be both impeccably refined and effortless.

Today: Fusion & Innovation

Today, Mathieu fuses the discipline of Savile Row with the fluidity of Italian tailoring. He dresses leading statesmen, top executives, bankers and financiers from the City of London to Wall Street, as well as renowned artists, Hollywood actors, and musicians. His approach integrates artificial intelligence and advanced 3D configurators to visualize proportions, materials, and finishing while preserving the soul of handcraft.

Whether commissioning a formal two-piece, a travel-ready soft jacket, a leather piece, or custom shoes, each creation is cut from a unique pattern, hand-assembled, and refined across fittings to achieve a perfectly balanced silhouette.
