Hoodies & Merch Store Beta

Seriously considering buying a glow Thresh hoodie from the new merch store, even if it is a bit pricey. But for me to dish out $90 on a hoodie (after shipping), I really wanna make sure I get the sizing just right. I'm 6'3", but I'm built like a pole. I think I should go for a large, just for the sake of having long enough sleeves. That tends to be a problem for tall skinny guys like me. Has anyone purchased one or seen one in person, so that they might be able to give me some insight on this matter?
