EZSkin allows users to add support for additional figures by adding definitions to the ezskin.xml file included with the distribution. Instructions for doing so are in the readme.txt file in the zip file.

There's no reason why a leather coat couldn't be treated as another figure. After all, leather is skin, sort of :-)

I'm happy to help more if you need it, but if you fancy giving this a try I suggest you have a go yourself first (it's quite easy, I think) and then if you get stuck at any point you can ask for specific help then.
