‘They’ decide everything. ‘They’ know whether it is to be pink or green this fall, whether it’s to be short skirts, whether you can wear mink. For years everyone who thinks has gone around at one time or another trying to find out in a desultory sort of way who ‘they’ are. One of the most fascinating things about the world of fashion is that practically no one knows who inhabits it or why it exists. There are a few people who know how it works, but they won’t tell. So it just goes on, getting in deeper and deeper, until something like a war or depression slows it up from time to time. But once the war or the depression lets up, off again goes fashion on its mad way.
