It seem like a poetic retelling of a basic truth. Girls (and boys as well) will do anything to fit in, but they don't realise that they are better han anything anyone could try to make them into. She will do something that ridiculous just to fit in and lower herself in such a way. She puts too much value in her classmate's opinions and easily succumbs to peer pressure. The difference between the rich girl and the one in the red dress is lying on the floor between them. Eventually she will realise that one she looks up to is nothing but a highschool whore and surpass her in every respect. I probably judge her but, it is looking to turn out that way.
