The 21st-century hipster is a subculture. Fashion is one of the major markers of hipster identity. Members of the subculture typically do not self-identify as hipsters, and the word hipster is often used as a pejorative for someone who is pretentious or overly concerned with appearing trendy.

A subculture is a group of people within a cultural society that differentiates itself from the conservative and standard values to which it belongs, often maintaining some of its founding principles. Subcultures develop their own norms and values regarding cultural, political, and sexual matters. Subcultures are part of society while keeping their specific characteristics intact. Examples of subcultures include BDSM, hippies, hipsters, goths, steampunks, bikers, punks, skinheads, gopnik, hip-hoppers, metalheads, cosplayers, otaku, otherkin, furries, and more. The concept of subcultures was developed in sociology and cultural studies. Subcultures differ from countercultures.
