You can visit our Chart to take a look at all our different blank types and sizes. The sizes listed use standard body measurements, ie: bust (chest for men), waist, hips, etc. Measure fully around that part of your body to know your measurements. Once you have your measurement, compare that number to our size chart and you should be able to find your appropriate size.
We also offer a Fit Guide with various models for you to compare size and body shape to in order to better help you find the correct size.
Please note that while we do our best to minimize this, 100% cotton shirts can shrink depending on the method of washing so if you are in between sizes you may want to order up to be safe.
