Standards of Beauty in Cinderella

In our society, the image of thinness equalling beauty is highly overdone. There are beautiful women of all sizes, not just thin. Yet if you look at runway models and high-fashion models, most are very skinny. Where do we get these ideas of beauty? During the 1600-1800's, when the Perrault and Grimm versions (respectively) of Cinderella were being written, women were not expected to be quite so thin, but they were supposed to have a slim waist and delicate features. In nearly every version you read or see of Cinderella, she was petite, with tiny feet that would fit the tiny glass or golden slipper. The stepsisters are usually portrayed as having feet too big to fit the slipper. But here is an interesting thing -- in Grimm's version of Cinderella, the stepsisters were told to cut a piece of their foot off to fit the slipper! One cut off her toe and the other cut off her heel. It was their own mother who told them to do that, because they wouldn't need their feet that much when they married the prince. No woman in her right mind would mutilate her body to get a man, right? That is what I thought and then realized that even modern women get fake breasts, nose jobs, permanent dye under their eyes, and probably a host of other things to get a man.
In Charles Perrault's version of Cinderella, called "Donkeyskin", he said that "Her waist was so small and fine that you could encircle it with two hands." Even if a man had big hands, that would still suggest a waistline that was unaturally small! That is why they had corsets to wrap women's waists so tightly. Thank goodness we no longer wear corsets. Doing some research on corsets throughout the centuries, I learned that they were not only painful but could be dangerous. Doctors warned of over-doing the corsets because it compressed the organs too much. In one article which I will attach here http://www.marquise.de/en/themes/korsett/korsett.shtml, it said that even babies and children were wrapped to begin to re-shape the soft skeletal structure into a "fashionable shape." That seems cruel and outrageous by today's standards. I was shocked to see that they did this to young girls. Maybe, hopefully, we have come a long way. But then I'm also a bit shocked when I see little girls in our society who are barely able to walk, and they already have pierced ears...
