hi. now that the sales going on I really want to buy some new shirts. but I'm having trouble deciding on what size.
usually, i wear a guys Medium(yeah, i know. chubbyyyyy.) but the past few "threadless"-type shirts I've bought have been too short. they fit fine everywhere else. but they're just too short. so, i'm thinking, get a guys Large. but i noticed on the size chart that its only a inch longer. so when i wash it won't it be too small again? and another factor is the width is two inches more. that might be too big. maybe i'm just over-thinking the whole thing.

but please help.
