How do you make body armor?

I used a plugin for it and failed horribly. Can someone help please?

What do you mean by 'body armor'? You need to be more specific then that, because I don't understand it at all. If you just want to look like you have armor then use meshes on yourself, but if you want something like parts covering your body, then you'd have to weld each part to the part of your body you want them on.
