Who has the final say on whether a person has a good figure or not?

Being a woman is not easy sometimes. Just considering your figure alone brings you pressure from all aspects of your daily life. After a long time, you may even feel a little confused. Who has the final say in judging your own figure?

Scene 1: There is a scale in the lobby on the first floor of the dormitory building where I live. When passing by there, I often see one or more girls lingering beside the scale and pondering for a long time. Some shake their heads and lament, while others jump for joy. I don't know who put this scale here, giving many girls the opportunity to feel stimulated from time to time. Isn't this too "humanistic"?
