Why It Matters
Get the Right Fit First Time
Every item is printed to order and made just for you, so choosing the correct size up front saves time. Use the measurements below to compare against a shirt you already own and love. The chart lists the finished garment measurements, laid flat.
Made to order: Because each piece is produced upon order, we recommend double-checking your size before checkout. If the fit isn't right, you can still use our 30-day return and exchange process — see the Return & Refund Policy page for details.

Measure in 4 Steps
1
Find a shirt that fits
Take a T-shirt you already own that fits the way you like and lay it flat on a table.
2
Measure the chest
Measure straight across, from under one armhole to the other. This is the chest width (flat).
3
Measure the length
Measure from the highest point of the shoulder straight down to the bottom hem for body length.
4
Compare to the chart
Match your numbers to the closest size above. If you're between sizes, size up for a relaxed fit.
