Size Guide

Find your size before you order. Two ways to do it: measure yourself, or measure a shirt you already own and love. Both work, and both are below.

Our shirts are a regular unisex fit in a standard length, cut to work for both men and women. The fabric is ring-spun cotton with double-stitched hems, so it stays soft and keeps its shape wash after wash. One thing worth knowing up front: these measurements come from the supplier and can vary by up to 2 inches, or 5 cm. A tape measure beats a guess every time.

The fit

True to size, regular fit, nothing oversized or cropped. If you usually wear a medium, a medium will fit you like a medium. The cut is the same across every design, so once you know your size here, it holds for the whole catalog.

Which size to pick

The shirts are unisex, so the same size lands differently depending on the fit you want:

Men: pick your usual size for a regular fit, or go one size up for a relaxed fit.
Women: pick one size down for a regular fit, or your usual size for a relaxed fit.

Measure yourself

The most reliable way. Grab a soft tape measure and take two measurements, then match them to the chart below. Points A and B in the diagram show where each one goes.

T-shirt diagram showing measurement point A for length and point B for chest width — A is length, B is chest. Use the same two points for the chart below.

A — Length: start at the highest point of your shoulder and pull the tape straight down to your waistband.
B — Chest: measure around the fullest part of your chest, keeping the tape horizontal.

Measure a shirt you own

Already have a t-shirt that fits the way you like? Lay it flat and measure it, then compare to the garment chart. This is the closest thing to trying ours on before it arrives. Same two points, A and B, measured on the shirt instead of on you.

A — Length: from the highest point of the shoulder, next to the collar, straight down to the bottom hem.
B — Width: from the seam under one sleeve, flat across to the seam under the other.
