Here are some screens I took to show what I mean:

I don't understand why the meshes float around her body like this. I've asked for help even adjusting them in blender, but I've had no luck figuring out what is causing this issue, and it has been present since I created this sim in 2019, even before I used custom content. Is there some solution to this? She also gets the odd "bulge" male sims have, which frankly bugs the holy wow out of me because she should not have that. I'm sorry if this isn't the place to post this, but it seems like a bug and it is pretty frustrating to not find a solution to it so far.
