How ironic. It’s actually entirely legal and not uncommon to see entirely naked people in SF.

You may need to update your priors. In Seattle, for example, going about your business naked in the city is not only legal, but determined to be a Constitutionally protected civil right by the courts decades ago. (And as is very evident, some people choose to exercise that right.)

In my country, there are places where everybody goes naked all the time. Not sure if people live their all year round, or if it is only for holidays.

Those places are not, for example, shopping malls.

Pretty sure they have shops there, as well. However, the people stocking the shops probably put on some clothes when they need to venture outside to get supplies.

Well I have never witnessed a mythical naked shopping mall, just some outdoor parks and gardens out away from most other people where only the clued-in would go. It is not ok to go out naked in public!

The ones I mean are more like camp sites. But I haven't been there myself. Isn't "nudist camp" also a thing in the US?

My reference for nudism is various parts of the Isar and Englisch Garten in Munich. In the US, nudist sites aren't really a thing, certainly not in any major city.

I know the Englische Garten. You can't go shopping in the nude there. I was talking about nudist camps. Afaik in the former socialist east Germany, nudist culture was actually a kind of rebellion against the government.
