Here the same set of P4 jeans without any modification have been conformed to the P4M on the left and Don on the right. I did have to set Dons legs & thighs to invisible to avoid poke-through, but otherwise the clothing fits moderately well without any alteration. For perfect fits, I think The Tailor might be able to handle this, but I've not tried it because I can get most things to work just with a few adjustments.
