Nice shirt but sizing is WAY off

This is a great looking shirt, but the sizing shown on the STP web site is WAY off. I ordered an M based on the guidance that appears when you hover over the sizes, which says it is for chests that measure 44-46 inches, but the shirt itself is only about 40 to 41 inches around the chest. I'm going to send it back and try an XL.
