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!
