But who is to say what is the perfect look?
Who says thin, or even anorexic, is good?
Who says what we should and shouldn't wear to look good?
Dressing to impress
I think the media is making all of us teenagers feel under pressure to look good, but for who?
Are we genuinely doing it to please ourselves?
I know I'm not.
Yes, it is nice to look and feel good once in a while.
But is it right to feel the pressure of waking up every single morning feeling that we have to impress everyone and anyone by the way we look?
It doesn't help to read magazines and watch television programmes displaying so-called 'perfect' celebrities.
The effects from displaying such material are depression, peer pressure, bullying and utmost jealousy, not just for girls, for boys too.
The sooner we all face up to reality and the fact that nobody is perfect, the sooner we'll all feel better about ourselves and learn to love the person we really are."
