Shiva is one of my dream costumes and I finally decided to take the plunge and cosplay her along with a big FFX group at Otakon 2010. This is probably the most expensive costume I'll ever make. The wig alone cost around $300.
I made everything myself, down to the bikini bottom, tassels, and "shoes".
The wig is one 51" base blue wig + 13 packs of blue, purple, and teal extensions wefted in over foam core. I used 20 yards of gold ribbon, one whole skein of blue yarn, and an entire bottle of Aquanet.
Body paint is PAX paint, mixed myself. It took 6 hours to put on and 3 hours to take off. This is NOT a costume for the impatient!
Most everything in this costume, including the wig, has a central core of wire so that it would stay where it was supposed to.
Not sure when I'm going to wear this again; it's a very uncomfortable costume, but I got some good photos and had a great time with my FFX group at Otakon. Thanks to everyone who took pictures of us and came up to me and told me they liked my costume. It means a lot ^_^
