The second method of fixing JCM poke-through is to stop the JCMs doing what they are supposed to do.

On V4, there is a dial called Deformers -> Strength. On V4.2 it is called Base -> Strength. This is usually set to zero, but setting it to -1 completely cancels out the JCM effects (also known as Deformers).

The image shows V4 with her arms up as before, but this time I cancelled out the JCMs instead of magnetising the clothing, so her breasts did not move with her arms.
