I could never understand why there are only the two types of clothing, conforming and dynamic.  It seems there could be a type of clothing that simply maintains its fit as the body is posed.  I suppose there would have to be a lot of vertex level checking to do this, but I don't understand why form fitting clothing has to have so much poke-through.  Just thinking that some kind of collision detection to keep the clothing mesh from intersecting the body mesh would be needed, but without soft-bodies many poses actually require mesh intersection. 

Maybe there could be some way of doing a depth sort of the body and clothing meshes; if most of a mesh is in front of another mesh, the mesh poking through would simply not be drawn.
