Fashion is forever changing and it seems so hard to keep up with it. We all know that fashion works in cycles and usually comes back as evidenced by present trends representing the 1980's. In the 90's we saw the 70's bell bottom reemerge.
In the first stage of the fashion cycle the trend emerges on the runway, red carpet, or in a music video. Next comes the time when the trend becomes very popular and everyone wants it. You'll see the trend in magazines, TV, and other media. Lastly, the trend takes over the market and you'll begin to see knock-offs of the product being mass produced.
So, what drives these cycles and how does that affect us as a society? It's a complex question with complex answers. There's a great article at Fashion Worlds that poses this question and seeks to give us a better understanding of what relevance the cycle has in Western society's consumerism.
