How do you add a vagina physics to armors in SSE?

How do I add vagina physics to (bottomless) armors without changing their armor slots in the CK? 

 

I want NPC's to equip these armors. I noticed that if they're using different slots, NPC's might try and equip them on top of their regularly spawned body-slot armors, and it looks weird.

if you  use SOS you can set an armor in MCM to be revealing and then it hides the body supplied with armor, or you can edit them in outfitstudio so only armor appears instead of armor body+your body.
