There was this one time a few years ago, I was in midsummer night's dream. I was one of the fairies, don't remember which one, but that was my only role throughout the whole thing. So the costume designer decided to go ALL OUT on my hair. There was glitter EVERYWHERE. I was washing it out for at least a month afterwards XD.
Well, glitter isn't impossible to get off. If you needed to go to an interview you'd be able to get it all out in time. I just didnt have to do anything so I didn't try.
