I really adore Rosario + Vampire, and if I were given the chance I would probably cosplay just about all of the girls from it!
The right shade of purple for the wig is hard to find, not to mention in Shirayuki's style! I'm all for styling wigs myself, but it was hard to find anything that was even close. So, I bought my wig at RamenCon 2011, since I really thought it was nice and cute, and I got to see it in person (where as ordering online can be iffy). It's a little bit pinker than I want, but it's still cute <3
