When did punk fashion start?

It first started with the bands like Ramones in the late 70's and early 80's but the punk style became huge in early 2000's. Stuff like Baggy Dickies, crazy hair, liberty state and Mohawks. Punk bands like Sum 41, Good Charlotte, Blink 182, New Found Glory have those punk styles back then and punk influenced fashion to be rebel and different. Wish we had it back!
