So I have a super old Cosworx Scruffy in a really light blonde, bought several years ago for a Bianca (from Pokemon) cosplay that never panned out. I think if I straighten it out so it's less flippy it would work all right for a Shiemi cosplay. The color is a bit lighter than the Natural Blonde currently available--more like a platinum blonde.
My only question right now is what outfit should I do for Shiemi? I'm thinking about the school uniform, because it would probably be cheaper than buying fabric to make her kimono, but at the same time the kimono is probably more recognizable.
