Non-mainstream means to publicize personality, be different from others, be non-mainstream, not blindly follow the trend of today's public, and pay attention to clothes, costumes, words and deeds that suit your own mind.

Non-mainstream refers to things that are not the most popular, that is, relatively advanced or backward.

In terms of the number of people, there are fewer people who pursue non-mainstream and more people who are called mainstream.

Where there is mainstream, there is non-mainstream. Mainstream and non-mainstream exist.
