Naked Europe covers up
I lived on the French Riviera in the 80s. Nearly all European women were topless at the beach, and in St. Tropez, there was full nudity. I recently visited, and the only topless women were older. None of the youth went topless. Fewer exposed breasts in advertising as well. No idea the cause, probably, instant global media has made them self-consciously realize few countries are that permissive.
