You are absolutely true. Girls normally do this only to ensure that the guy gets henpecked gradually and sits like a dog licking her feet for whatever she does. This is what is called vanity. And for that matter a boy keeps doing all to her pleasure until he gets his pleasure and then starts doing what he likes. It is all a matter of establishing supremacy over the other! Girls, be sensible. It is entirely not personal to you on how you wear and appear in public, and Boys, beware that you cannot just hand around every girl you see. You stop seeing the girl, they will start wearing properly and behaving normally.
