Which has the distinct advantage, of course, of being very customisable. It does tend to require hairspray to make it stay in though, particularly if your hair is very fine.

Another option would be a full wig. I'm not sure how I'd manage that with bubble wrap; I haven't worked with wigs much. Also a full wig can get very heavy if there is a lot of plastic involved so you ahve to be careful with things like neckstrain.
