Girls as young as 3 have already learned to place a premium on their physical appearance

In a survey of 170 children, girls were more likely than boys to pick fancy outfits and say they liked certain fictional characters because of their looks.

Women are under more pressure to look good than men. For instance, the top trait that women are valued for is physical attractiveness, according to data from Pew Research, while men are most valued for their morality and honesty. Meanwhile, 71% of Pew survey respondents said women are under pressure to be physically attractive, while only 27% of respondents said the same about men.
