In this paper we consider ambiguous character of the fashion.Change is the essential of the fashion. But for people who are now in a fashion
movement, fasion is not a faint value. Fashion is a change but a style about which many people are enthusiastic. The difference between a viewpoint in a fashion and a viewpoint out of a fashion divides the views on a fashion. This ambiguity has confused a series of attempts to describe a
fashion. We are apt to watch one side of a fashion. But we should try to discuss and describe both reliability and unreliability of the fashion.
