Need help skin not updating

I’ve been trying to render my character and my rig for blender seems to not work with 1.8 skins. Basically, I had to redesign my skin with the jacket/pants being the SAME texture as the REGULAR legs and arms and body, so that my render would still look the same as if it had the jacket/pants or not. However, in order to GET that new skin, I don’t know. I tried searching my username and it came up with my skin BEFORE I changed it (the 1.8 skin), and now I can’t find my new edited version that works in Blender.
Please help me find my current skin, not my old one!
