People usually pay their attention to fashion because it's really cool to feel yourself well when wearing clothes that are really attractive and beautiful, when the other people look on you and admire your clothes. Moreover the person dressing by rules of fashion will always know he is looking good and so the most righteous way to look beatiful every time is just follow the rules of the fashion.
Of course, there is lots of pros and cons anyway, and not an every person would like to dress by fashion. Sometimes this dresscode reaches unnormal view of clothes and it's not comfortable to wear it. So, anyway, i just want to say that every person has its own taste and it's absolutely his rights how to dispose it.
As for me, i don't like following fashion because i like wear what i like and i don't want to follow someone's rules what to wear. I find it silly and see now sense to dress myself as someone's (в данном случае someone has, а не чьи-то, мало ли надо без сокращений...) said, doesn't it look stupid?
