How do I get rid of underwear? - SOLVED

[Fel558 18]

I am trying to replace follower's body with a SAM body but I am getting black underwear.

How do I get rid of this?

I mean permanently. Since this is possibly a conflict with the follower in question as it comes with it's own SOS files but it's not the first time I've seen it. I just don't want SAM being able to assign this underwear mesh. Is there away to remove the mesh and texture files?

EDIT: It was late, I was frustrated. It didn't occur to me that the mesh I was looking for was an obj on the body already. Now I just need to fix my schlongs which I seem to have broke uninstalling and reinstalling things
