Dress Code...?

It's something that causes confusion...dress codes. Ok, I'm not a sort of rebel that doesn't accept a business man in a company wearing a suit, or a bride wearing a formal dress, or people caring a bit for their image. I just don't understand when that becomes fanatism, and perhaps when that makes people label each other. I understand that looking good is nice and even healthy but why does society establishes so many rules and so many of them unnecessary about clothing? Why must we attend a weading, a job interview for a company without sneakers? Why must we use a certain kind of clothes when we're 20's and another when we're 30's? I'm I not a grown-up unless I wear high heels? If I'm 24 and my regular dress code is jeans, a t-shirt and sneakers, does that make me not a woman, am I still a kid and for that I'm I not supposed to be respected as a mature person? Am I not a good doctor, engineer, teacher, (translator!haha) unless I dress like society is expecting me to? Then why are designers, artists, musicians able to dress like they want to and are not (much) criticised for it?
Well, maybe I should be a musician or remain forever a kid :)

Hymn to Friendship

...because friends are the best we have.They share our joys, our insanities, our sorrows, our hysterical moments and they always stay around. They can be apart for so many days and yet they still know that they can count on each other no matter what time brings. And not diminishing the importance of my other friends, because I really love you and need you all so much!...here, today, I want to say that I miss you particularly...our jabardations, our conversations..to you today I dedicate this song because it's so full of magic, the song and the book that stands behind the movie...You I miss. And to you goes "Eloi" - Klaus Badelt [The Time Machine] **
