Copied and pasted from my blog: http://living-for-the-sake-of-it.blogspot.com/2012/01/oiran-hair-piece-tutorial.html
Hatsune Miku and Kagamine Rin from Vocaloids
So, while trying to recall my plans for the day, I shall make this very random blog post of how I did the back hair piece for my Miku cosplay *points abouve pic* this version.
In this song, Miku is an Oiran [花魁]
If you google it, you will see females with those huge hair piece on their head. Like really huge?
When I decided to cos this version, I didn't see anywhere selling the wig. The style, yes, color? nope. OTL
