I'll be cosplaying the White Violin from the Umbrella Academy, and am planning on using my own hair because it's similar in cut and color. My hair is already an ashy platinum blonde, but when I paint myself white, it won't look light enough.
Compared to white:
Any ideas to temporarily lighten my hair?
I can tone it white as a last resort, but I'd really rather not if I don't have to, because I'd have to do it myself the night before and that could be disastrous.
