I based my measurements for the hoody on two hoodies I own, and was wondering if there would be a way to change the size if it doesn't fit when I get it? I chose the LG, which will likely fit me, but I just wanted to know in case it's too big. The MD seems like it'd be more of a closer fit, but I do like my hoodies a little bigger for room. Also, I love all your designs for everything. They are beautiful, and I can't wait to get everything!
