Hair Cut Styles And Tattoo Designs

The nerdy emo look - (best for girls under 17 and guys over 21)
Short hair. Style it messy, but not spikey.
Horn-rim/thick black frames/cat eye glasses (this works for all three types).
Thin, tight, solid dark color v-neck sweaters. I call them Grandpa sweaters.
Band shirts.
Messenger bag covered in patches and pins (that you bought at Hot Topic but you tell everyone you got them at shows).
Dickies work pants. Blue, black or grey only!
Argyle socks.
Black converse shoes.

The themes underpinning the Emo revolution will never go away. They will always be prominant feature of mainstream youth culture. Emo, as a catch-all phrase, will eventually phase out and be replaced by a new word-of-the-day befitting the emotional character of the times.
The term "scene" has become popular since the emo subculture kicked off. Scene kids or scenesters I believe are more about the style and looking like an emo without the personality of it all. In other words, scene kids are the ones that dress emo, but only because it's a trend or you could say Scene is Emo without the emotion. The term is subject to a significant debate like emo though.
