Hey everyone,
so lets get right into it.
sometime ago, i used to download this "nude mod" for the sims 4. which basically puts away the censorship etc.
its working fine, but the problems are, that my sim is ALWAYS wearing her underwear (bikini thing) in when shes changing to nude. (shower, etc)
now i downloaded this mod wicked woohoo, same thing.
can someone please tell me how i could fix this?
and sorry for grammar mistakes (im not a native english speaker)
thank you for reading!

You have some faulty cc causing this. Use sim4studio batch fix. But do remember to take out any anatomically correct skins from your mod folder first. I have cmar's in my game and forgot to take them out before running batch fix and my blokes went back to barbie bodies....LOL i forgot how weird they look without their real bits in place.

I experienced that with Wicked Woohoo too. If you are ever going to have new female sims either newborn from pregnancy or created in Cas from child, teen adult, then take Wicked out when you do. It has a very old glitch that Cmars "nude in Cas" mod once had over 18 months ago.

That any female generated in the game would be assigned clothing for shower. In truth, sims always wear clothing in shower, but it's an invisible set of top and bottom clothing when it works as it's supposed to. That's why, if it glitches from CC or mods, we see the clothing. And Wicked assigns the "wrong clothing." So even if you clear up the problem for adult sims, then get rid of mods and/or CC that caused it, many sim days or months later a baby girl still grows up to wear wrong clothing in shower for the rest of her days. The Cmar nude in Cas has long since been fixed and causes this no more - certainly not in my game. But I noticed Wicked did it recently. I think the creator of Wicked only tested on existing sims, did not test on newly made sims to spot this old wrong clothing issue.

To fix, take Wicked out, use one of the methods to reset bathing clothing. I use scumbumbo's clothing tool to force bathing to be true naked again (Invisible clothing). Then put Wicked back in. But know for as long a Wicked is in your mods folder, all newly created females - even newborns - will be assigned wrong, visible clothing when naked - until the creator fixes this issue.
