@hamsterbellbelle I've never seen something like this happen before. Do you use mods or custom content? Is there any pattern to either the career or the everyday outfits that the sims are wearing when they get this bug?
Regardless, you'll probably have better luck asking about this issue on the Sims forums. Plenty of players use cc and spend a lot of time designing and planning outfits; I'm sure someone will be able to help. If you're not a member, you won't be able to start your own discussion there, but I could start one for you if you like. Just let me know your username over there.

You could also ask at Mod the Sims, although I'm not as familiar with that community.
