Your challenge, should you choose to accept it, is to come up with an ATL in which the views of popular society, with regards to clothing and the lack thereof respectively, are reversed; an ATL in which, for the vast majority of the world's population, being fully clothed is more stigmatized than being fully nude, and still remains so by the time that TTL reaches the present day. Which PODs could possibly bring this about? How early would these divergences have to be? And how unrecognizable would the world in general be as a result?
