Fashion

While doing research in class today, I found one of the few articles to be particularly interesting.  I ave never really thought about fashion designers and why they design/sell the clothes that they do.  This article answers that question, saying that some people sell clothes according to trends and others according to the quality of the clothes.  This makes me wonder how do they figure out what kind of trends will be popular in the future and how do they know customers will buy their product?  Also, what makes the quality of a piece of clothing good?

This is a Uniqlo store, showing many different colors and trends.
