Is Fashion Art?

Has anyone seen the new show at SAM, Future Beauty: 30 years of Japanese Fashion? It seems to be making a case for fashion as an art form. I know a lot of you use fashion as an outlet for creative expression, and I feel the same way. Do you think of fashion design as a legitimate form of art? It certainly expains for me why some fashion is unwearable.

BTW, my first time starting a topic.
