I've said this before, and am writing it again as I believe it bears repetition: Fashion is a multi-millon dollar industry. Although clothing more advanced than a toga or a sarong may be perceived as unnecessary by some, it's no more unnecessary than any product that is 'designed' to be attractive beyond its essential usage, be it a car, door knob, book or house, so why people persist in thinking of fashion as self-indulgent nonsense is beyond me.
