Ask yourself, What is fashion? Why does it transform periodically?
The first thought that ignites: maybe this transformation takes place because the fashion industry influences our choices seasonally. Contrary to that belief, if you really do consider the factors that come into play with regards to evolving styles and trends, a predominant factor is us: All of us. Human beings undergo constant evolution when we evolve our likes and dislikes evolve with us. Thus this concludes that before trends are set, we unconsciously have already chosen to be a part of their evolution.
