KJSharp saidI don't get it. Do they expect people to wear this stuff?
Not always. Fashion is like the riskiest of the clothes someone can wear. I mean, outside of the fashion hubs you'll never see anyone wearing it day-to-day.
However, it creates a ripple effect. Take for example, leather pants. They show up in fashion runways. Then more approachable designers do waxed jeans. And then even more approachable do black jeans with a shine. And the bottom ringer does black jeans. That's how a lot of people end up wearing black jeans.
It was hilariously explained in The Devil Wears Prada, a roman-a-clef of one of Vogue's editor's assistant, and masterfully played by Meryl Streep.
