LOL, I do prefer the grey, though I only had white hair extensions to make it with. I'm going to look into dying them greyish sometime in the future, but there is so many other cosplay things I need to get finished that I'm happy enough with how it is right now that it's not priority.
holy shit. That looks SO nice.
And that's basically what I'm going to do when I do Xigbar... although as nice as the white looks, I think I'm going to use grey :3
