Women are held to impossible standards for appearance.
There is always someone, male or female, ready to tear a women apart with words.
Look at celebrities. One wears an unusual outfit or cuts her hair and people are commenting. OMG how could she do that. She looks horrible.
Men call women ugly fat bitches when they get rejected or simply to harass women.
When you look at the people they are talking about, in reality they don't look ugly at all. Young women so upset about their nose or hair or some other feature because a parent, sibling, boy, girl has said something nasty to them and they decided to believe it instead of considering the source.
So what I'm saying is, instead of internalising what someone says, tell yourself and write it down that is only their opinion. Consider the source. Was the person being rude and trying to cut you down?
Why did they feel the need to say something to you? They were trying to hurt you and make you feel bad.
If this continues to bother you, see about getting some CBT to have the skills to deal with the bs people heap on women.
Women with self-esteem have power and are less able to be manipulated.
