What does cosmo mean?

COSMO means metropolis in American slang, and there is also a kind of "cosmopolitanism" and self-awareness in it.

As a fashion COSMO with strong self-awareness, they are white-collar workers and high-end scientific and technological personnel in the company, as well as otaku and post-80 s. They refuse to compromise easily and pursue perfection, but they also know how to advance and retreat. They pay attention to appearance but don't deliberately play cool. They are picky about life details but advocate low-carbon environmental protection.

Cosmo's popularity is not only popular with the media, but also has its own uniqueness.
