When enough people copy it, it becomes a fashion trend. After too many people copy it, it is not longer fashionable. This is why it is all bad fashion. It is only a matter of timing when good fashion turns to bad. Fashion spoils the same as cheese. But some cheeses taste better when they are aged and left on the shelf for many years. These are the same with some fashions, they get better with age. Of course they are still spoiled by too many people liking them, but they transcend to becoming “classic fashion” just like a very ripe 10-year-old aged cheese.
If this seems too cheesy, then consider fine red wine. How is it possible that the older it gets the better it gets? Wine never goes out of fashion, because they can just bury it in a cellar for the next hundred years and when they pull it out once again, it will be a marvel. Some fashion ages like wine, but not all of it. The vast majority is bad fashion, which is only as good as a bunch of bananas that will soon be rotten and need to be replaced. The fashion that lasts is the classic fashion and it is hundreds of years old. Just like the fine wine, the classic black and white tuxedo is even better than the first day it was invented. But this is the minority.
If the majority of fashion is bad fashion, then how does one know whether to invest in fashion or not? The truth is you cannot invest in fashion, you can only get ripped off by fashion, unless you are a pompous designer that puts their name on everything and sells their name as the investment. That is the height of fashion. Take a $5 baseball cap, that you have made in China for 27 cents and put your designer label on it then charge $200 for it and have all the kids in high school trying to find $200 to buy it because it is the fashion.
It is bad fashion, but almost all fashion is bad fashion. Put that same $200 baseball hat on some dilettante head that is famous only for being famous, like the hotel chain girl or the K-girls and then get a photo of them wearing it, get them to sign it, and then you can sell it on eBay for $2,000. That is the height of bad fashion. Still all the guys want to be with these girls. This means that bad fashion is good.
