So I am 5 feet 8 inches, and I want a jacket that's big but not heinrik status. I don't want something that fits just right, but I don't want it to be a dress, I just want it to be big. Do I get a medium or a large saga jacket? This is uber important bc if I need a large I need to look around and hunt on the buy/sell/trade page, but if medium will work then I can get it online.
