Q: Ok, so if I have about a 36 chest and sizes are Small- 34" - 36" and Medium- 38" - 40" Do you think I should get a small or a medium, I'm ordering over the internet so I can't try it on. Yeah I think I'll do that, I just didn't want it to barely fit me. Well, I'm done growing though, and i wouldn't gain weight just to fit into a shirt.
A: you should get 38" cuz it will probably run small, but if it doesnt and its to big than you can grow in to it.
