Want to know more about the emo look... does anyone have any tips or advice on cosmetics? Colors, where to buy, and what to look for?

Have you tried googling it? I just did and found a ridiculous amounts of links about the music scene and style...

If you have a Hot Topic near you. Bingo. They have a lot of bright Makeup etc.

Well I am emo, not to the full extent but I wear black eyeliner + mascara with different color eyeshadows (depending on the outfit)

I would say go with what you think looks good. Express yourself

Go to VideoJug - Life Explained. On Film. - it's better than YouTube [in my opinion].
