How to dress like emo, when I am not emo?

I really adore there hairstyles and all that. These couple of days I’ve been wanting so badly to dress, put on make up, like emo people. BTW, Iam a black girl from African and I don’t have long hair so I don’t think there is anything I could do to my hair to have the emo hairstyle:(
Anyway…What do you guys think of this idea?? and what colors should I wear? black??
