I will see what I can come up with. I will have to search for a picture first, then I will check out some site I get my wigs from. ^_^ Possibly the costume store 5 mins from my work...to see where or what they suggest. ^_^
Edit1::
If you can get this one as blonde (not two toned) this might work.
punk spike wigPlatinum blonde is as close to white you can get without it being white. If you would like for CosWorx I can show you a pic of a planinum blonde wig.
This one has a bit longer hair, which you could cut to how you like it.^_^ I would again suggest platinum blonde.
longer punk wig(Both links are from CosWorx, cosplay.com's wig shop.) They do sell good wigs, I have bought wigs from cosworx before. ^_^
