Punk fashion was originally an expression of nonconformity, as well as opposition to both mainstream culture and the status quo. Punk fashion often displays aggression, rebellion, and individualism. Some punks wear accessories, clothing or have tattoos that express socio political messages. Punk visual art is artwork associated with the punk subculture. The main aesthetic of punk visual art seems to be either to cause shock, to create a sense of empathy or revulsion in viewers, or to make a grand point with acidic or sarcastic wit. One characteristic associated with punk art is the usage of letters cut out from newspapers and magazines, a device previously associated with kidnap and ransom notes.
