Punk look

Punk over the years has incorporated many subcultures and substyles. Regardless of these, the core is always a sense of rebellion and controversy; something meant to shock. In today's fast world, sock is something that is much harder to do.
Which is one of the things that weakens punk fashion as a full blown fashion trend. Wear punk in the same way that Sid Vicious did and you risk looking like you're playing dress ups as opposed to being something of a rebel.
That's the first problem with punk fashion as a full blown fashion trend. The second is that many of the common elements of punk have already had plenty of exposure over recent seasons as a part of other trends: leather, military / combat, bondage / fetish, ripped stockings, and tattoos (which are now completely commonplace) are some examples. There's so much cross over that, while punk certainly warrants a mention for spring / summer 2011, it by no means stands in isolation.
Hence for 2011, no matter what you read, the punk fashion trend should be less about an overall theme and more about mixing punk elements with other seasonal trends. For example, something ultra-feminine with a punk-rock edge.
