cookie are you using a cracked or premium account? Some websites have ‘skin usernames’ such as mcskinsearch which a cracked user could use and have a skin. Sometimes these skins change(varies from username to username) and some never do. One example is Piratebooty, he uses a username like this yet his skin has always stayed the same. I used to use one that changed the skin every once in a while before I got a premium account. Of course, that’s only if your cracked. ._.
