I believe girls judge other girls more

Hello, First of all iam a boy. Whenever iam out with my girl in public like in a club or pub or any other place even some McD or KFC and we are having our fun. I see a lot other girls judge her and look at her if she is smoking or wearing some dress which shows a little or more cleavage. Sometimes boys do not look or stare but almost everytime there is a girl sitting at a distance staring and giving heavy judgments about her or her clothes. and lets not just talk about aunties whenever she is smoking at a street.
