When I was verifying the problem with the coconut costume swimsuit, I had set the underwear in the relation command back to default and forgot to disable it.
I turned off nudity, which eliminated the cutting of the body in the underwear.
I'm updating the partcutdesc.xml in the top post so you can download it.
My edits affect the entire character. That is to say, it includes male characters.
If you don't like this and want to edit them individually, please put the following line in the character thing
If you are using my partcutdesc, put it in the "Body_cut" field. If not, put it in the "Fish_Hand" field.
