The changing nudity culture that is German
Some while back, sunbathers in Germany, say on the river banks of a city, would be about 2/3 fully nude. Circa 2023, they are 100% wearing bathing suits or more.
I believe the causes here are threefold: a) a Woke/prudery effect, b) an international conformity effect, and c) a fear of being posted on social media or circulating as a jpeg effect. The increased number of migrants to Germany is possibly a fourth factor, especially when people go in groups.
