How Dress Shirt Sizes Work
How Standard Sizing Works
Dress shirts rely on two measurements, neck size, and sleeve length. The neck size appears first, and increases by half inches range from 13" to 19". The second number is the sleeve length. Every shirt has two length options that depend on which of the buttons you are using on the cuff. A good dress shirt manufacturer will also provide a chest measurement range within a given size.
100 years ago, you (or your tailor) knew more than just your neck and sleeve length, but mass production needed a way to standardize sizes that maximize output for soldier's uniforms.
Manufacturers used the neck size and arm length to inform mean measurements for the torso and garment length to create the standard sizing we still see today.
How Sizing Should Work
The industry standard is far from perfect leaving those with athletic and skinny builds swimming in fabric. We measured thousands of lean and athletic guys and discovered that a man’s height and his torso shape are the two key factors in determining a perfect fit.
These two essential factors are routinely ignored when it comes to mass-produced menswear. This realization led us to create a totally new sizing system, including 12 sizes inspired by guys just like you and our commitment to better-fitting menswear.
