What is fashion?

Actually, the fashion industry is very influenced by trendsetters and cool hunters.
Designers, fashion brands, marketing companies all have to lookat what is fashionable.
They have to look at what the trendsetters and cool hunters wearing.
The designers make a lot of different products because in different neighbourhoods, there are different ideas of fashion. Clothes, shoes and sneaker prototypes depend on the neighbourhoodand what is fashion there.
What is fashion? Fashion is what the trendsetters are wearing, but does it look good on you?
Also, there are people that are wearing fashion clothes but they aren't trendsetters. They are fashion victims, because they don't look good in the new fashions. For example Lady Gaga is a trendsetter but who can wear her style?
Another example is Kate Middleton, she is a trendsetter but her clothes are always very expensive.
Everyone cannot be fashionable all the time.
