Whilst I am choosing to look that way, Butterbur, you are willfully misunderstanding the reason why I am choosing it. Perhaps if you put in a lipring it would be to try to make yourself look daring. When I do it's because I like the way it accents my lip. It is not unusual to me in the way it is to you; many of my friends and family have piercings and tattoos and dyed or spiked hair. If I specifically wanted to look different in my family, I would go and shop in muted colours from Next or something.
The idea that I want people to judge, too, is ludicrous. I spend half my life asking people to question why they make the assumptions they do. Everybody judges, it's true - stereotypes are how you understand the world. The dangerous part comes when you start believing those split-second judgements are always true and start behaving based on them.
And no, I don't judge the Boden-wearing masses as bourgeois and boring. Partly because I wouldn't recognise Boden if I fell over it as my knowledge of clothes styles and labels and stuff is ridiculously poor...but mostly because I know that just because I consider the clothes boring to me doesn't mean the person inside them is boring. Clothes really do not maketh the man. They clothe the man. I do raise an eyebrow at people who wear those things specifically because they want to blend in, in the same way I raise an eyebrow at those who wear things like me because they want to stand out. Your appearance should be chosen for your own approval, not that of others.
I should also probably note, I said I wear the mohawk half the year. The other half (in the winter when a hawk just isn't worth the effort) my hair is usually dyed black and in a short, dull style (in my opinion)). I also switch between wearing things like a plain hoodie and jeans to bondage trousers and a tie-dye shirt. I am happy in those different things because I wear what I like, not what I think others will like or dislike.
As for doing something interesting, I do plenty of interesting things. I also like to catch sight of myself in a mirror or look down at myself and think, "I like that." Do you honestly consciously choose to dress yourself in a manner you consider dull, or do you - like most people - choose the clothes you think are interesting?
