A new thing in costume appears--the flaring hoopskirt, for example--and the passers-by are shocked, and the irreverent laugh. Six months later everybody is reconciled; the fashion has established itself; it is admired, now, and no one laughs. Public opinion resented it before, public opinion accepts it now, and is happy in it. Why? Was the resentment reasoned out? Was the acceptance reasoned out? No. The instinct that moves to conformity did the work. It is our nature to conform; it is a force which not many can successfully resist. What is its seat? The inborn requirement of self-approval. We all have to bow to that; there are no exceptions. Even the woman who refuses from first to last to wear the hoopskirt comes under that law and is its slave; she could not wear the skirt and have her own approval; and that she _must_ have, she cannot help herself. But as a rule our self-approval has its source in but one place and not elsewhere--the approval of other people. A person of vast consequences can introduce any kind of novelty in dress and the general world will presently adopt it--moved to do it, in the first place, by the natural instinct to passively yield to that vague something recognized as authority, and in the second place by the human instinct to train with the multitude and have its approval. An empress introduced the hoopskirt, and we know the result. A nobody introduced the bloomer, and we know the result. If Eve should come again, in her ripe renown, and reintroduce her quaint styles--well, we know what would happen. And we should be cruelly embarrassed, along at first. The hoopskirt runs its course and disappears. Nobody reasons about it. One woman abandons the fashion; her neighbor notices this and follows her lead; this influences the next woman; and so on and so on, and presently the skirt has vanished out of the world, no one knows how nor why; nor cares, for that matter. It will come again, by and by; and in due course will go again. Twenty-five years ago, in England, six or eight wine glasses stood grouped by each person’s plate at a dinner party, and they were used, not left idle and empty; to-day there are but three or four in the group, and the average guest sparingly uses about two of them. We have not adopted this new fashion yet, but we shall do it presently. We shall not think it out; we shall merely conform, and let it go at that. We get our notions and habits and opinions from outside influences; we do not have to study them out.
