Women of the Apatani tribe living in the Ziro valley, Arunachal Pradesh used to have wooden plugs lodged in the sides of their noses as a rite of passage. However, instead of adding to their beauty, the practice was initiated to make them uglier. Officially abolished in 1970, it was historically started to deter tribal raiders from kidnapping and taking away the beautiful women of the tribe.

When colonialists arrived in the Americas, they were shocked by a painful beauty standard for native women: plucking off all of their pubic hair. Thomas Jefferson said of this foreign tradition that "with them it is disgraceful to be hairy in the body. They say it likens them to hogs. They therefore pluck the hair as fast as it appears." When it's put like that, I guess it might be worth the trouble.

In the 18th century, the previous standard of bare-faced women disappeared, and women began wearing heavy makeup. They also started wearing beauty patches, small pieces of fabric that were adhered to the face. They came in many shapes, such as stars, circles, and squares, and their placement on the face had specific meaning. For example, one by the mouth implied flirtatiousness, and one on the right cheek meant that the woman was married.

For thousands of years, Japanese women would blacken their teeth permanently after marriage. This continued through the 19th century, and was a symbol of beauty and marital commitment.

For European women during the Middle Ages and the Renaissance, the plucking did not stop at the forehead. Eyelashes became symbols of oversexuality, and the fresh face was in. Thus, women of means would often remove their eyelashes entirely, which sounds way too painful to begin thinking about.

Thanks to nylon shortages during the second World War, women's pantyhose were lacking. However, the tan appearance of stockinged legs was still considered necessary, so dozens of paint products meant to mimic the look of nylon hit the market. According to a 1942 edition of LIFE Magazine, "When they are properly applied the most scrutinizing pair of masculine eyes cannot distinguish between legs thus covered and legs in sheer hose." However, some women would just go for what was around and use gravy to paint their legs to get that stunning nylon look.

The Chinese have a long history of long nails. Both men and women of the Qing Dynasty grew nails that were 8 to 10 inches long, and some women wore gold nail-guards in order to protect their rather inconvenient manicures. This was to indicate that they were wealthy enough that they didn't need to labor with their hands. Instead, they had to rely on servants to do things like dress or feed them.

Starting around 1000 BC, the ancient Maya started modifying the skulls of their infants. A child's head was kept strapped to a board or bound with various implements, forcing the skull to become malformed. This was done to both males and females, and it is believed to not have been related to social standing, but a sign of ornamental beauty.

King Henry VIII, for example, was renowned for his excellent calves.

Worn in the lower lip, the clay lip plate is the defining image of women across the Mursi and Surma tribes in Africa. As soon as the girls of the community hit puberty, their two lower front teeth are removed and a hole is pierced in the bottom lip that is then stretched out to accommodate the lip plate. The size of the lip plate gradually increases over the years, as they believe that larger the plate and lip, the more beautiful the woman is.

The ancient Chinese practice of foot-binding, believed to have started around the 10th century, has long been abolished. However, there was a time when Chinese women underwent this painful practice to remould the bones of their feet into the customary size of three to five inches, by binding them. These ‘lotus feet’ were believed to be the beautiful symbols of status and wealth in society.

Before the Industrial Revolution, pale skin was usually considered the standard of beauty in European cultures. After the Revolution, however, it was tan skin. In both cases, the association was with wealth. Prior to industrialization, pale skin was evidence of a life of luxury; instead of working in the fields, you were able to lounge in the shade or under a roof all day. After industrialization, this reversed. Now pale skin was the mark of the underclasses, who worked in factories all day, while tan skin evinced the luxury of being able to stroll about outdoors.
