This chart refers exclusively to work clothing: how women dress for fun is outside its purview. This is a measure of how much effort a woman is expected to make with her appearance while she’s trying to make a living, taking heel height as a fair proxy for overall work. It’s astonishingly consistent once you notice it.

If you are an actress/model who makes a living from her art, you fall more into the star/supermodel category. Your feet may still hurt, but at least your apartment is comfortable.
