Ok, well here's my idea for you, but as you can see.... Its REALLY expensive, but it is the most accurate cosplay.
You could subbstitute the hair however, to something of a little less value since the hair is the most valuable item. And since the avi looks a little plain, you could still throw in a few other items...
Hope I helped ^.^
