[HelloDiDi]

Oh, music is my 1st love, alas I only ever learnt to play the recorder and tenor horn! but I've always loved music, especially live; my era is an eclectic mix of late 70's/80's so disco, prog rock, electronica, underground house, mod, late punk, 2-tone/ska, new wave, romantics, metal, rock and pop; basically, if it was a good tune/lyrics I'd like it 
Look-wise I used to mix and match so always had an odd look mixing a few girls clothes with my boy clothes, actually, I probably looked a right mess, but hey-ho the joys of being young 

It was the same here, although each genre had their own look I found them quite accepting to different styles as long you had your own individual look and it wasn't a pastiche of their look, I'd get stares and lots of interesting conversation with many a lass. Although, like you say, there was always the underground hardcore niche/clique where it had to be their way or not at all!!

Let's keep pushing those boundaries 

You sound quite like me as that's what I do all the time unless I'm at work. Mix and match rules. As does breaking the rules.
