Look, open a program like Photoshop and paste this png into it and apply it to your skin. It is important that your second layer on the body and arms was not, because if there are still details on the second layer of your skin with the clothes will be bugs.

Then you go into meinkraft and see if it fits you or not. If you have a skin in the style of alex, then I can make him and the same clothes, but a little smaller size.
