Hi all, I seem to be having a spot of bother can anyone tell me how in SimPE I can use an existing clothes mesh or custom clothes mesh on a custom body mesh, like zenmann's for making a big guy in a trenchcoat, hope y'all understand what I means by this, cheeryo

You don't use simpe. You use bodyshop.
Make 2 recolors - one of the outfit that has the design (graphic) you want to use
then make a recolor of the new mesh.
Copy the graphics from the first project into the second one.
refresh it.
if it looks great, import it into your game.
if not, you will need to actually edit the graphics.
You can learn how to do that in the bodyshop/skinning area
