I have the same "poke through" problem when I use collisions. You would think that they could implement some sort of "covers" function and eliminate morphing and conforming entirely. The only morph would be how tight or loose. For example, point at a bra and indicate that it covers the chest and collars "tightly," or point at a skirt and say that it covers the hips and buttocks "loosely". Oh well, maybe in Poser 6!!!
