Okay 'classism etc' but you really do know what im on about here.

Why do people the majority would describe as 'chavs' still exist? I mean, why are there so many people still wearing adidas tracksuits and hug earrings these days? It doesnt mattter what class they're from or anything, im just saying by the clothes they wear, not what they say or anything. Its just its been ridiculed to death but people are still wearing these things and it doesnt seem to be irony... whats going on?
