I've seen Rocky Horror twice by amature groups and both times the whole audience dressed the part (admittedly one was a student performance so any excuse to dress up!!) I just assumed that is the done thing when seeing this show?
I'm going with some friends to see the official performance of it and when i mentioned dressing up the friends were shocked and had never considered doing that (they haven't seen it before)
So, over to the MN vote - do you dress up for rocky horror or not?!
