Well, the glam image is pretty much the biggest aspect of Glam Rock or Metal as a "musical" genre, and although a lot of people say "No, man! It's about the fucken music!" I really don' believe that, and since it is called "GLAM" it's definitely ALL ABOUT THE IMAGE! Oh, and the SEX, too!
I DO love the music, though
Personally, the way I dress is all inspired by the glam metal musicians. I've gotten my inspiration from David Lee Roth, The Crue, Poison, and a shit load'a other bands. I also think improv is the best way to go with dressing glam. Just wear any old pair'o skinny jeans, but I like skin tight ass-huggers especially colored ones and leopards. You can even tie a bandanna on yerr leg, er something, coz that's what I usually do. When it comes to shoes, I recommend high tops. A lot of glammers do like cowboy boots, but I really don't like them. I also like wearing headbands, like leopard prints, and bandannas on my neck. If yerr comfortable with it, you can even try wearing a bit'o make-up. I'd wear eyeliner, but it really doesn't look good on an Asian guy (yepp, ME!)With upper-body clothing, you could just wear a band shirt err something, but you can also wear a tight biker leather jacket, v-necks, silk vests, denim vests, and as I said, just come up with yerr own style! FUCKEN IMPROVIZE!!!
All the shit I said was pretty retarded, but that's just the way I dress, so yeah... Hope it helps, but I doubt it, coz I'm just a retarded kid in a glam site
