Naked Girl Naturists On A Nude Beach

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.
In some hunter-gatherer cultures in warm climates, near-complete nudity has been, until the introduction of Western culture, or still is, standard practice for both men and women. In some African and Melanesian cultures, men going completely naked except for a string tied about the waist are considered properly dressed for hunting and other traditional group activities. In a number of tribes in the South Pacific island of New Guinea, the men use hard gourdlike pods as penis sheaths. Yet a man without this "covering" could be considered to be in an embarrassing state of nakedness. Among the Chumash peopled of southern California, men were usually naked, and women were often topless. Native Americans of the Amazon Basin usually went nude or nearly nude; in many native tribes, the only clothing worn was some device worn by men to clamp the foreskin shut. However, other similar cultures have had different standards. For example, other native North Americans avoided total nudity, and the Native Americans of the mountains and west of South America, such as the Quechuas, kept quite covered.
In 1498, at Trinity Island, Trinidad, Christopher Columbus found the women entirely naked, whereas the men wore a light girdle called guayaco. At the same epoch, on the Para Coast of Brazil, the girls were distinguished from the married women by their absolute nudity. The same absence of costume was observed among the Chaymas of Cumaná, Venezuela, and Du Chaillu noticed the same among the Achiras in Gabon.
