Not sure what size you are? Finding your hat size is simple! Take a flexible measuring tape and measure horizontally around the widest part of your head. This spot varies from person to person, but on most it's about half an inch to an inch above your eyebrows. Measure three times and take the average of those three numbers. That's your size!
Using a flexible measuring tape or string, measure over your clothes around your hips. Make sure that you keep the measuring tape horizontal as you wrap it around your body. Find the size belt that contains your measurement in its range.
Exact custom sizing is available at an additional cost. Select the "custom" option from the drop down size menu and specify your exact measurements in the "comments" field.
