how do i make clothes using UV Map??

how do I put clothes/armor on my model using uv map???

after you unwrap, you use an image that looks like armor as the Texture. See Painting in the wiki user manual. you will want to expand the skin vertices (inflate in sculpt mode) to make them bigger than his body so it looks like they are ont the outside of him, and not tatooed to his body. Have fun!
