I had the same problem for 3 days, then I asked in a support group and they give an object named "av bug fix". Inside this box you can find 2 folders that are 2 outfits, wearing them consecutively and then putting on one of my outfits it works!!
The problem is that after 2 days the problem was back again and I had to redo all the procedure with "av bug fix".
I have tryed doing a ticket to LL but they only send me the link to this forum.
If someone need this "av bug fix" you can contact me in world even if I think this is just a temporary solution.
