Along with the images of the apparel, each item will have a sizing chart. This image may help understand the measurements on the sizing chart:
Body Length: Distance in inches from the shoulder seam down to the bottom of the garment (length of the body).
Body Width: Distance in inches from the stitching of where the sleeve connects to the body on each side.
Tip: Measure a well-fitting shirt or sweatshirt you currently own lay it flat and measure from side to side just underneath where the sleeve connects to the body of the garment and compare with the WIDTH on the size chart.
*Due to the nature of t-shirts & apparel production, each item does have a 1/2" tolerance which means it may be slightly bigger or smaller in either direction*
