Ancient Greeks, for example, were obviously very comfortable with nudity, as reflected in a lot of their art. On the other hand, Islamic cultures value modesty much more. And of course there are countless other cultures that range in between.
Why does this happen? One of my guesses would be temperatures, that if it's warmer in a place they would be more comfortable wearing less clothing, but isn't it warmer in the middle east than in Greece?
Another factor that I thought about was religion, as Greek mythology was often more crude than the Islamic stories. But are the cultures more modest because their stories are more modest or is it vice versa? Are there other factors that weigh in that I didn't mention?
I suppose by "modesty" I mean the extent that the culture is comfortable with exposed bodies. Greeks, for example, made plenty of statues and pieces of art of naked people, but Islamic cultures emphasize more modest, concealing clothing and dress.
I chose the examples of Greek and Islamic cultures because they were the first ones that came to mind. Sorry if I said something incorrect. I'm very curious about this topic and eager to hear what you have to say.
