My favorite bands are all angura/eroguro, but not necessarily their looks.
My favorite
visual styles would probably be of certain indies visual kei bands. I don't really like the vinyl/leather/black/gothy look too much, because after a while it all begins to look the same. It's hard to find originality when everyone copies everyone else. Even Vidoll, I love the band, adore the music, but their look does nothing for me.
Lately I've been looking at some stuff, and it's things like this that catch my eye:

This is a band called Gift. I like the clothing a lot. And the hair. And the makeup. More than anything though, the colors of the picture, heh.

This is the vocalist of a band called eL'trip. I saw this and fell in love with the hair (since I'm looking for something to do myself). I haven't really seen anything.. too similar to that.

This is Billy. I just like how it all.. pops at you.
smile A band you've all probably seen already is SID. The photosets they were selling at Acen 2004, that was pretty nice. I think Alicenine have similar makeup/hair, but I don't really see anything special there.. they all kinda look the same ._. I'm not saying the pictures I posted are that 'original', just.. something I don't see too often.
