Chest width is most important to me, and about 20-20.5 inches across is ideal for me, but what exactly does Woot mean when they say the shirts are a bit smaller than one might expect? Should I get a Large if I want basically a 20" width chest? I’m confused. I’m just afraid I’ll be expecting 20" and get like 19" by the time the shirt is taken out of the dryer or something. Although I can air dry if need be.
