How to Use The Size Guide
All measurements are taken with the shirt laid flat:
-
Width is measured across the chest, from one armpit to the other. To calculate the full chest circumference of a shirt, double that number.
-
Length is measured from the highest point of the shoulder (near the collar) down to the bottom hem.
If you're between sizes, we recommend sizing up for a more comfortable fit.
Pro Tip: Measure a shirt you already love and compare it to this chart for the best match.

Please note: There is a ±1 inch tolerance on all measurements to allow for natural variation in the sewing process.
