Hey everyone! Well I finally got my shirt today!!!! Communist Party :D

Anyway, I got it in a small since I like my shirts to fit rather than be swimming in them. I'm a bit worried it might be a tad too small though, but I don't want to jump up to a medium and have it like, toooo big, ya know? Anyway, for anyone that knows the difference, is the medium that much larger than the small in both fit and length and all?

thanks!
