Anti-fashion
Anti-fashion is an umbrella term for various styles of dress which are explicitly contrary to the fashion of the day. Anti-fashion styles may represent an attitude of indifference or may arise from political or practical goals which make fashion a secondary priority. The term is sometimes even used for styles championed by high profile designers, when they encourage or create trends that do not follow the mainstream fashion of the time. This anti-fashion was adopted in response to the 'overly fashion conscious' fans of bands such as the Sex Pistols.
