the one with the fashion

can anyone define what is fashion? what is the correct sense of dressing? went down to town yesterday night. saw a group of young punks(as i would described) with multi-coloured spiked hair. i must really salute them for their courage to be able to even walk out of their house in that way. call me old fashioned or whatever but you would never catch me in that or what so ever. another dress sense that i detest is guys wearing jeans with slippers or sandals. what goes with jeans have to be covered shoes. that's my own opinion though.
