I bought my brother a large size long-sleeve, and now I'm wondering... He says he usually wears a medium (somewhat snugly), but I figured that since American Apparel sizes small for girls, it might be the same for guys. He's pretty stocky, so I don't want him to look too awkward. :)

The shirt is huge -- how much will it shrink in the dryer? Or, if not at all, should I return it for a medium?

Guys out there, I need your help! Thanks!
