While the fashion industry may, at least at the top end, be thriving, the notion of fashion itself is becoming more and more meaningless. Any discipline in fashion has long since evaporated; the idea of a single fashionable skirt length, or heel height, is incomprehensible. The definition of the fashionable has become so skimpy that it refers not to the mode of dress of everyday people--the clothes that have sufficiently caught the popular imagination to be worn in a widespread manner--but only to the styles that momentarily excite members of the fashion caravan.
