fashion tribes means: Fashion has shifted away from a single style that is universally flattering for everyone. Instead, different segments of the public, particularly the younger ones, will likely wear clothes that reflect their style tribe or group. This phrase was probably created by Ted Polhemus, a writer. Some of the most well-known youth style tribes include punks and goths as well as hip-hop lovers, ravers, and fans of hip hop. (in Fashion Dictionary)
