If "fashion" had any value, it wouldn't need to be changed every year. Classics endure because they have inherent worth, and can be worn for decades, with only gradual, minor changes taking place as the old clothes wear out after long service.

But this does not provide employment for those whose business is to convince you that you need something new just because the style has changed. So fortunes are spent (and made) by trying to convince people they should give up what they are wearing for something else.
