I've tried the "choice" method - as in "Do you want to wear this shirt or this one?" etc. but she doesn't want to wear anything at all. I don't think it is a tag/texture issue because she doesn't have tags in her clothes and most of her clothes are extra-snuggly soft.
Any ideas (besides turn up the heat - since it is warm already, I will have trouble convincing my husband to get it in the 80s) ???
