Crin- I was able to get a picture of a couple of the offending sims who are floating heads. They are adults. I have both a male and a female in the future. I was only able to fix their outfits with MC. I went to basic, remove outfits (everything except naked and singed), then I went to Advanced, reset sim. This fixed them. I did place the clothing pedestals in my home world and when a sim was browsing it (she was an adult also), the invisible head appeared and then it switched outfits. My friends who just got ITF are reporting problems with not just clothing, but some of the female accessories as well. As soon as I get ITF installed on my PC, I'll test the outfits more (my mac got an OS update today and is now unplayable with sims).
