Hello, good evening. I thought the coat was bigger and that's why I ordered the XL size, but when I tried it on it turned out to be a little big and I would like to know if I can exchange it for the same one but a smaller size. So please tell me anything because I have the cover and the packaging here that the order came in. Thank you.
