fashion: art or usability?

i think that fashion is both art and usablility. we started wearing clothes to keep us protected from the weather and diseases. today, most people see clothing as an art. it certianly takes a lot of time and planning to accomplish a simple peice. people use clothing as a way to express themselves and make themselves look and feel better. fashion can also be used as a status symbol. for instance who is wearing the biggest designers and who has more expensive things to show off. All in all i think clothing and fashion can be whatever you want it to be.
