Dear Carly, So here's the gist of it - The song is written from a 17 year old girl's perspective but I think the reason why the song has resonated with so many people is because it's about something that everybody deals with - that being body image/self-esteem issues etc... It's said a lot and it sounds cliche but we do live in such a time where physical appearance is a huge factor in every day life and it gets destructive when, in reality, we were all made differently with different bodies and minds. But there is this underlying pressure for us to be Brad Pitts and Heidi Klums walking around.
