This costume took me about two weeks (and a whole lot of relearning how to use my sewing machine).
Used a shiny, metallic spandex for the entire thing.
Also learned how to make boot covers like a boss.

I'll be making a different pair of Sais as the ones I have are cheapos, bought right before the con. I want them a bit more accurate to the cover I based this costume on.

The wig is from Epic Cosplay Wigs.
