The best way to ensure that you get the perfect fit is to take an old t-shirt that you (or the one who this is for) are using today and compare its measurements with our t-shirt sizes chart.
Width
This is the measurement of a t-shirt lying flat on the ground from armpit to armpit - sometimes this gets confused with chest measurement, which goes all the way around your chest, but this one is just the front of the t-shirt.
Length
This is the measurement of the back of the shirt, from top to bottom. This should give you an idea of the length of our fits.
