So far, then, we have, as the great and dominant norm of dress, the broad principle of conspicuous waste. Subsidiary to this principle, and as a corollary under it, we get as a second norm the principle of conspicuous leisure. In dress construction this norm works out in the shape of divers contrivances going to show that the wearer does not and, as far as it may conveniently be shown, can not engage in productive labor. Beyond these two principles there is a third of scarcely less constraining force, which will occur to any one who reflects at all on the subject. Dress must not only be conspicuously expensive and inconvenient, it must at the same time be up to date. No explanation at all satisfactory has hitherto been offered of the phenomenon of changing fashions. The imperative requirement of dressing in the latest accredited manner, as well as the fact that this accredited fashion constantly changes from season to season, is sufficiently familiar to every one, but the theory of this flux and change has not been worked out. We may of course say, with perfect consistency and truthfulness, that this principle of novelty is another corollary under the law of conspicuous waste. Obviously, if each garment is permitted to serve for but a brief term, and if none of last season's apparel is carried over and made further use of during the present season, the wasteful expenditure on dress is greatly increased. This is good as far as it goes, but it is negative only. Pretty much all that this consideration warrants us in saying is that the norm of conspicuous waste exercises a controlling surveillance in all matters of dress, so that any change in the fashions must conspicuous waste exercises a controlling surveillance in all matters of dress, so that any change in the fashions must conform to the requirement of wastefulness; it leaves unanswered the question as to the motive for making and accepting a change in the prevailing styles, and it also fails to explain why conformity to a given style at a given time is so imperatively necessary as we know it to be.
