It only ever came in xs, m and l to my knowledge unless it was special ordered. I would really look into that with the seller. Ask without letting them know you know this and see what they say. Perhaps it was special ordered however that is more rare than common (if that makes sense). If you buy this and it turns out to be a fake and then you need service from VCA, they will not help you. Also make sure there is the paper work with this (mind you, sadly even now this is faked). Good luck.
