How It Works
  • Create a Custom Size

    Our sizing algorithm has been honed over tens of thousands of fittings by expert tailors for a precise fit that's more accurate than simple measurements.

  • Shop Online

    Choose from our exclusive selection of hundreds of fabrics, and select your ideal details like the perfect collar.

  • Expert Review

    Our master tailors will review your profile in detail before your first shirt goes to cutting.

  • Custom Production

    We cut and sew your shirt in about two weeks in our American production facilities and ship right to your doorstep.

  • Perfect Fit Guaranteed

    Over 90% of our customers get a perfect fit with their first shirt, but if you need any adjustments we'll alter or remake your first shirt for free.

Our Prices

More Shirt, Less Brand Markup

Our goal is to offer the best value in custom shirts by investing more of the shirt’s retail price in the actual garment, not in expensive marketing campaigns, splashy photoshoots or big brand markups.

We run lean too. Our CEO? Also our web designer and photographer. Our customer service team? All of us. We do this so that we can offer our products for a smaller markup than our competitors, meaning you get more shirt for your money.

Our Sizing

Expert Tailoring, Enhanced by Machine Learning

Our sizing algorithm is the most accurate in the industry, built with advanced machine learning, honed over thousands of fittings, and refined by the judgement of master tailors.

But, we still believe in the unmatched value of human experts, which is why every new client has their own dedicated Fit Advisor to provide expert guidance regarding sizing issues, and to provide a detailed review before their first shirt goes to production.

It's the best of both worlds, for a fit that's second to none.

Our Quality

Ethically Made, Built to Last.

We choose to work with factories and fabric mills that have a long heritage of quality, some right here in the US.

Our partners employ highly skilled and fairly compensated men and women, many of whom bring decades of experience and craftsmanship to their trade.

Thoughfully designed for the way you live now.

Times have changed, and so should custom clothing. We’ve ditched the ostentation in favor of a more casual approach rooted in quality and durability.

Dress up, down, or somewhere in between—we've got you covered.
