sittingbear, you're right, I haven't done that and don't even think I know how to do that

igazor, I found it interesting that when the two recently married sims went to the bedroom, got naked and woohooed, then got off the bed, still naked and entered the living room, they were suddenly dressed, as if I had the dress code mod active (which I didn't because this was their vacation home), yet perpetually naked sim, stayed naked when entering the same room. So the problem is definitely with this one sim.

Well Woohooer has a setting to Change Clothes on Room change enabled by default so that explains why the 2 married rooms had clothes when they got to the living room.
And are you using Dresser I think I remember having a simular problem but mine was my sim would leave the house and go to school naked and anywhere else for that matter after taking a shower.

LOL that's funny.   No I don't use dresser. I know the problem is a game glitch, I would just love to know how to clear it. I have reset her with both DE and MC but nothing has worked so far.

Try redoing her outfits with Stylist if that doesn't work try CAS and if that doesn't work well I guess you just have a sim that likes to walk around in their birthday suit.

I already changed her outfits in both CAS and stylist and it didnt work. Shes about to get married, so she'll  be moving to another house. Hopefully that will solve the problem. If not then I'll  have to live with it. Thanks for the suggestions. I appreciate everyone's input
