At M31N, every collection is crafted with thoughtful intention—from responsibly sourced fabrics to small-batch production.
We reduce waste through precision tailoring, and ensure each garment earns its place in your wardrobe for years to come.
Our limited-run of just 31 pieces per style is not only a statement of exclusivity—it also means we make less, and make it better.
Sourcing Responsibly
Most of the materials used to create and protect M31N products are derived from nature — from animal, plant, or mineral origins. Because not all of these resources are renewable, we are committed to supply chains that actively restore biodiversity.
Our focus is to preserve natural resources and the climate, ensure animal welfare, prevent deforestation, eliminate hazardous chemicals, and reduce air and water pollution.
This year, 82% of our materials were responsibly sourced through verified and traceable partners.
Sustainable Materials
We collaborate with partners and supply networks that help rejuvenate land, foster biodiversity, and enhance soil health — all contributing to greater carbon absorption and a positive environmental impact.
Our goal is to continuously improve the sustainability of our sourcing by prioritizing regenerative and low-impact materials. By 2025, 77% of our materials already meet our responsible sourcing standards — certified or recycled under rigorous environmental criteria. As part of our circular approach, we are also developing new materials such as bio-synthetic leather made from mushrooms and other innovative recycled fibers.
Crafted to Last
We believe true craftsmanship is at the heart of responsible fashion. That’s why we work with generations of artisans and designers who combine technical mastery with a shared vision for a more circular future.
The artisans in our ateliers preserve and pass on their over 40 years of exceptional know-hows of haute couture— keeping its craft long-lasting while advancing sustainability.
From pattern-making to prototyping and construction, the passion and precision of our master craftspeople ensure that every M31N piece is made to endure.
