What is fashion photography?

Fashion is an innovation; An idea is concretized and then sought after by countless people. Whether it will be popular is uncertain. It should be said that most of them don't, and only a few are suitable for fashion. Moreover, many people wear it and use it, so it can't be called high-end fashion. Imitation and similarity can only be regarded as the primary stage. Fashion is as vague as Yin and Yang in China Taiji, and it is really hard to explain if it is too literal.
