Draw a line from the Urals to the Indian Ocean. Draw another across the top of the Sahara. It's a lot of land to the NW of that line. Over 3000 years, the evolving cultures number in the scores at least. They had different points of view on nudity, and at the same time viewed the nudity of children differently than that of adults, and that of slaves than free persons.

Take just the ancient Athenians. All those naked statues, especially of athletess. They had no problem with it, everyone thinks.

Nope. Thucydides remarks (c.411 BC) that until recently, the Olympics had been conducted in loincloths at the least. Only the recent adoption of Spartan habits had them competing in the altogether. Going commando was only adopted around that time, for most Hellenes. As for women, they called Spartan women "thigh-flashers" because they didn't sew their chitons into tubes, but used the original rectangle of soft wool open down the left side. That never flew in the north or Ionia.

On the other hand, the Persians were a very body-hiding culture, generally covering to the wrists, ankles, and neck, by their artwork - both sexes.

The Gauls were supposed to fight stark naked, in some reports. The Egyptians got sexy by putting on wigs and makeup and jewelry: nudity was a neutral workaday state to them. The Sarmatians of the steppe cover up as much as the Persians and Medes.

So you have to pick a time and place.

Islam steps on nudity pretty hard: they may have acquired it from their subjects of the old Persian Empire. On the other hand, Christian peasantries might ignore it. The Irish were considered savages by the British because they would work naked in the summer fields as late as the 1800's, and their women would strip to full cloth.
