I saw your avatar and was wondering if you'd respond to this thread! I've spent a lot of time thinking about what color I would use for a Bride wig. I had also read that Elsa Lanchester's hair was reddish-brown and frizzy/curly. According to several sources, it was her own hair, and not a wig. They used a "hair cage" and brushed her hair over and around it. The white pieces were supposedly made separately. It's been a while since I sat down and watched the movie, but I had assumed that when Lanchester was playing Mary Shelley, her hair was slicked back into a bun. Either that or they cut it short after filming the Bride segments, and filmed the Mary Shelly parts later on, with the new haircut.
It's not too difficult to get my hair frizzy, and I think it would be a decent color if I wanted to do the costume that way. If I could learn how to make one of those hair cages and secure my hair at the top, I could probably do that without too much trouble. The skin tone might be fun to match though.
Like I said, I could reroot the wig, but how would I get the hair to stay upright/secure the top?
The other option I thought about, was doing it in black and white, so instead of trying to get the right greenish palour, I could just use a light gray base, black hair, etc.
