Welcome to the forum, rebel. Like TM said, it depends on the brand. Thea best thing you can do is try things on. You should also know your complete measurements (chest, shoulder, sleeves, etc.) so that if the shop provides measurements for what you're looking at, you'll know what you need. There is no sizing standard across be board. Best of luck.
