Hey gals and ghouls!

Okay so im stuck; im going to see horrorpops and more rocka bands next week and i want to dress the part..

i need ideas hairwise; see i work till 5 and the concert is at 6 so i have like 0time to prepare; and my preparation time will be on the bus or work mirror. So i need a kool hairstyle that can be done simply and quickly or something i can work with all day (imagine VERY VERY busy print shop.)

Hair currently is; brown with black streaks, naturally straight and about 2inches below shoulder level..

Ideas?
All welcomed smile
