Here is a nice Arsenal shirt & sock pairing. The shirt measures 20 inches straight across from underarm to underarm (40 inch chest) and is 26 inches long. PLEASE NOTE!!!!!!!----Many clothes makers, of course, would tag this shirt as a sz Small given that the chest only measures 40 inches. DO NOT WORRY ABOUT THE TAG SIZE-----ALWAYS, instead, pay more attention to actual measurements as opposed to tag size. Nice value on this Arsenal pairing. I wear a size 8 or 8 1/2 sneaker and these socks are nice and snug on me. There is no size on the socks, so that is why I share my shoe size and the comfort I experienced when putting them on. Very nice gently used Arsenal treasure------at a great price. HAPPY SHOPPING!
