Easy and quick gothic or punk hairstyles?

I'm being a gothic/punk girl (tween-ish age) for my schools halloween play. I need an easy, very gothic hairstyle that I can do in under 30 minutes. My hair is blonde, slightly curly, and around shoulder length. Although I have temporary hair colour (black and blue), its very unlikely that I would be able to use it. Any tips? I need them ASAP, 'cuz the play is this friday, and I need to know by wednesday
