Theodore Dalrymple describes the modern fashion for slobbery as snobbery:
A century ago, there would have been one clothes shop for every hundred well-dressed people. Nowadays there is one well-dressed person (if that) for every hundred clothes shops. What accounts for this strange reversal of ratios?
Beyond the fact that clothes are now mass-produced rather than made individually, there is an act of will involved. Practically everyone now dresses not merely in a casual way, but with studied slovenliness for fear of being thought elegant, as elegance is a metonym for undemocratic sentiment or belief. You can dress as expensively as you like, indeed expensive scruffiness is a form of chic, but on no account must you dress with taste and discrimination. To do so might be to draw hostile attention to yourself. Who on Earth do you think you are to dress like that?
