sizing chart. Our garment sizing chart provides information about the most common items included on Easy Sell Spirit Wear Programs — short sleeve T-shirts, long sleeve T-shirts and sweatshirts. It explains the sizing for youth garments from small to large and adult garments from small to 5XL. The sizes are measured in inches — a standard unit that everyone can understand. To find the correct garment size, all you need is a cloth tape measure. Simply take height measurements from the top of the shoulder down to where you want the bottom of the garment to fall. The width measurement should be taken from armpit to armpit. Compare the measurements to the garment sizing chart to know which size you need. It’s that easy! We want your spirit wear to fit just right, so if you still have questions or don’t see the garment you’re interested in listed on the chart, let us know! You can give us a call at 1-877-6-WINWIN (694-6946), and an account representative will help you out.
