These relatively stable costumes are, commonly, pretty strictly and narrowly localized, and they vary by slight and systematic gradations from place to place. They have in every case been worked out by peoples or classes which are poorer than we, and especially they belong in countries and localities and times where the population, or at least the class to which the costume in question belongs, is relatively homogeneous, stable, and immobile. That is to say, stable costumes which will bear the test of time and perspective are worked out under circumstances where the norm of conspicuous waste asserts itself less imperatively than it does in the large modern civilized cities, whose relatively mobile wealthy population today sets the pace in matters of fashion. The countries and classes which have in this way worked out stable and artistic costumes have been so placed that the pecuniary emulation among them has taken the direction of a competition in conspicuous leisure rather than in conspicuous consumption of goods. So that it will hold true in a general way that fashions are least stable and least becoming in those communities where the principle of a conspicuous waste of goods asserts itself most imperatively, as among ourselves. All this points to an antagonism between expensiveness and artistic apparel. In point of practical fact, the norm of conspicuous waste is incompatible with the requirement that dress should be beautiful or becoming. And this antagonism offers an explanation of that restless change in fashion which neither the canon of expensiveness nor that of beauty alone can account for.
