The 3rd pic is reggae, I assume
This is a very interresting topic, and I've always thought there was something in it.
I always thinks that I have a little clue about a persons music taste when I look at their style and because of that, I tend to think that everyone listen to music, at least people in my age. I keep on forgetting that it's many people that doesn't have an interrest in music at all too, so that often shocks me when somebody says they're not into it at all.
But then we come to the people who listen to music and you can see it in their style. They don't even have to have dress full-rock or full-punk or whatever. Not 100%, but they still have those small things in their style, like eg. Converse-shoes are the ultimate picture on it! What does they tell? You're interrested in (mostly) rock music, take it with long hair and and some worn-out jeans, are we talking grunge? And when we're talking about grunge, the thing with this music genre was to give a sh*t about fashion, that's why they dressed like this, but then again it become a trend and if you like grunge now and dress like that, you actually GIVE a sh*t about it, since you dress in those Converse's and worn-out jeans because of the music taste. That's a paradox.
There's so many other music genre's too, it would be a looooong post to resume them all.
Talking about myself, the music genre closest to my heart is grunge (yep, it is

). I don't dress grunge all-over, but I have a lot of it in my style, like worn-out jeans, lumberjack shirts, Converse's, layers, big sweaters... when grunge became my fave music, it wasn't like I decided to start dress like I do with all these things you would connect to grunge, it was more that it automatically came into my style, parts of parts, not suddenly. And it mixed with all other things that also came partly into my style and what my innermind felt beautiful and related to me. Eg. '70s old-school rock is also close to my heart, which lead to bling rockstar coats, leather, (fake)fur, boots, brown colours and flowerprinted dresses (okay, groupies to the '70s old-school bands

).
When I'm shopping, I don't think whether those shoes fits in under grunge or '70s old-school rock or not. It's more that my eyes actually found
those shoes because of what I already was inspired of in my head, which was those music genres.
When I was 14-15 I had this period of my life where I DECIDED to be goth, to just
suddenly start to wear only black, and
suddenly just start to listen to goth rock and metal. That didn't work. It's not like that it works when you start dress music=fashion. Trying that, and you will always end up like a fake poser wannabe.
