This shirt feels very comfortable. I'm 6'0", 190 pounds, 46" chest. I have L (bust 48 inches). Coofandy shirts are true to size. Now I have several of them. just don't use a dryer!Only iron on low heat.I have an iron "all materials", but if you don't have one, just take it to the dry cleaner's so that the design doesn't melt.Absolute recommendation!
