Punk is not a way you look, it's a state of mind. It's not mohawks and DIY Jackets. Typical Street Punk clothing may include mohawks, liberty spikes, combat boots, bondage pants (usually plaid), and leather or denim jackets. The MOST important thing I will tell you is just because you have a mohawk, doesn't mean you're punk. I myself had a mohawk, but I did it for idols(Tim Armstrong, Lars Frederiksen, etc) not for fashion. Punk is truly a mindset of independence. The freedom America provides should let us do anything, Anarchy if you will. No stereotypes are true. 'A punk has a mohawk and wears combat boots,' Henry Rollins from the legendary Hardcore Punk band 'Black Flag' is very simplistic. Once again punk is not a fashion, but a mindset.
Person 1: Look at that guy! He's doing whatever he wants to!
Person 2: That's pretty punk.
Person 1: That guy is abiding by the rules, but he's got these huge spikes on his leather jacket.
Person 2: Poser punk.
