I'm a girl and a mustang fan. I'm small but I ordered xxxl for comfort and also heard that they are a bit small. It came in and was more like a big one, but that's ok, it's comfortable and loose. I will be wearing it when I register my new Ford Mustang with dmv. I'm a little nervous because I don't think the guy who sold it to me was the real owner and I think he rushed for the title, which is illegal. So I'm a little nervous about any issues with registering and getting a title for my new Mustang. This is a guide and I look forward to learning how to use it. So I think if I wear that and show that I'm a crazy car fanatic, maybe they'll have more empathy or something.
