For a lady you can use the a transmap with either P4 thinstrap dress or the catsuit. For a gent it gets a little more tricky, I ran into that problem when creating Gilgamesh and ended up using one of Judy's dynamic skirts fit to him by using the cloth simulator. What version of
Poser do you have? With conforming clothing it may be more tricky getting one of her skirts to fit him properly.
