Sabaku no Gaara
Descriptionmy cheapest so far is my Gaara cosplay, on which I spent $20 on eBay and bought a long coat and $5 for canvas fabric. I cut and hand-sewn the vest and used one of my old black pants and that's it. Oh since my pants were long enough to cover my heels so I just wore my sandals.
As for my giant gourd, I asked my ex-employer for a bunch of air bubbles and some paper tapes and Wah-lah! There it is! All I spent was about 3 days to make it.
