Naked Girl Naturists At The Lake

In many Muslim countries, public nudity is illegal.
Historical overview
It is not clear when humans started wearing clothes. Anthropologists postulate the adaptation of animal skins and vegetation into coverings to protect the wearer from cold, heat and rain, especially as humans migrated to new climates; alternatively, covering may have been invented first for other purposes, such as magic, decoration, cult, or prestige, and later found to be practical as well. For men and women, public nudity was at least permissible in ancient Sparta, and customary at festivals.
