Our Story

Welcome to PRINCIPLE M — a premium menswear brand founded in 2013 with a mission to create timeless clothing grounded in quality, craft, and style.

We specialize in bespoke, made-to-measure, and ready-to-wear garments, complemented by carefully curated accessories and lifestyle pieces. Our style is classical with a modern sensibility — designed for function, elegance, and lasting relevance.

Our founder, Justin, found his passion for menswear while working part time United States, where he developed a deep appreciation for tailoring and classic menswear. What began as a personal passion evolved into a professional pursuit, leading to the creation of PRINCIPLE M.

At the heart of our workshop is our head cutter, who brings over 20 years of hands-on experience in cutting and tailoring. His precision, discipline, and quiet mastery ensure every garment begins with a strong foundation — one that reflects both the client’s needs and the craft’s highest standards.

We also believe tailoring is more than just product — it’s about people. Over the years, we've built a vibrant community of menswear enthusiasts through workshops, trunk shows, and social gatherings. Based in Beijing, we’re proud to be part of a growing classical menswear movement — and now we’re bringing that same spirit to the world.

After many successful years in China, PRINCIPLE M is expanding and offering our products and services worldwide through our website and virtual tailoring services. Whether you’re visiting us for a fitting or ordering online, our commitment to quality, fit, and service remains the same.
