Eventually MCCC and S4S got their features to help combat this glitch and I haven't seen it my game in a very long time. I could always get any sim back to being properly nude with scumbumbo's mod. Yep, even MCCC did not have its Dresser module and its copy/paste feature back then, so, so long ago. Copy naked from one sim who I made properly naked in any outfit I could, usually swim, then paste it onto a sim whose 'bathing outfit' (as naked is referred to as in the game coding for outfits) was plagued with clothing. Back then, the first successful method I started to use to fix it was to use the mod scumbumbo released to copy and paste clothing from one sim to another. Years ago, when the sims first started wearing clothing in showers, Sims4Studious did not yet have batch fix option to help try and fix it.
