Fashion

According too Simmel, fashion allows for us to express our own personal choices while still following society and its norms. I have seen how on a "level playing ground" fashion is still arranged so that there are differences in groups. For example: There are schools where dress codes are enforced and all the students have to wear the same outfits to school. When all the kids are dressed the same, how is it that they look so different? They still find ways to express themselves so that they don't look like everyone else. What do you think it would take for students to stop trying to dress so differently from one another? Do you think that if we lived in a true Communist society according to Marx that this would be attainable?
