Who We Are

At Mizzen+Main, we believe what we wear to work reflects what we think of work. And we think work is fun. We think it's a place of joy, collaboration, discipline, laughter, the ups and downs, and everything in between all of those things. That's why we make clothes that make people comfortable. We make clothes that let people breathe and stretch and move and think. We make clothes that let them work. And we have a good time doing it.

Founded in 2012 with the belief that there is a better way, Mizzen+Main is a premium men's brand with product rooted in performance fabrics and tailored silhouettes. Mizzen+Main is a multi-channel brand, comprised of our Ecommerce site, Retail Stores, and Wholesale Partners across the US, with our headquarters in Dallas, Texas. Our values are simple and guide everything we do: we have commitments, we think big, we act as owners, we're people too, and we never settle.
