Typical hipsters (well according to stereotypes) wear tight destroyed jeans, tight black blazers, indie rock band t-shirts, Converse All Star shoes, obscure jewelry, messy hair... But among people dressing like that, not all have the hipster mentality.
I must admit myself I am totally fascinated (aren't we all in a way or another) fascinated by their culture. Hipster guys ARE attractive, there's no denial about that. They were cool for a while until they got torn apart by disgusting comments regarding their rich upbringings, their lack of knowledge and their snobbish attitudes. They are interesting to hang out with. Their looks inspire tons of runway : Marc by MJ, Dior Homme... They do rule the fashion scene. And then you've got the hipster poster childs : Chloe Sevigny, Lou Douillon... And seriously we are incredibly influenced by them. We like them because they're "different" from the bunch of rich that flaunt their cash, they look dirty without really being dirty. For those who fear commitment (ex.: if you go for the punk look, there's no turning back point), they know they can somehow manage to be a bit more accepted by the real underground crowd and also be accepted by the upper class.
They're not hippies, and they're also not upper class people (because they're not supposed to look like they do, that's the whole point behind their style).
I know we've been pointing out a lot how lame it is to actually be rich and spend money on looking poor (BOBO chic). Of course now that the whole idea has totally shooted to become mainstream, it has come to the point where it is ridiculous. But initally, I see nothing wrong with trying too "look poor", if it is what you are vying for, if you are against all those bunch of rich poseur, and in a way want to rebel against it, it's a way of doing it.
Any concept is initally very interesting, but it all falls apart when too many people fall into it too deeply. It suddendly transforms into an annoying ideology.
