What`s wrong with not being popular especially if the basis is just your physical attributes which is really shallow. You just have to be yourself and embrace that quirkiness or "weird" sense of style because that makes you unique from them and stop degrading yourself by thinking that you don`t look "right". There are other ways to be popular which are more impressive like those involving talents and intelligence. If you`re going to change, do it for yourself and not just to be part of the "popular" girls.
Simple and Sober but elegant and Classy.
Suiting to the place I am in.
