It's hard to say exactly how much I spent, since there was a lot of extra stuff bought, and some things I bought but haven't or will not use. Also some was used for my sisters costume.
Here is a general brake down.
Gloves ($13)
Boots ($40)
or
These ($55)(they were not in my size, but I got these for my sister)
socks ($7)
Cordura ($12 per yard) maybe 2 yards used
Spandex ($12 per yard) maybe 3 yards used
Mask (~$30)
Worbla
Totaling these items, plus a small amount of Worbla puts the cost near $200. You might be able to find a cheaper spandex you'd be happy with. And the boots and gloves are optional, you can almost go with whatever you like there.
Also, keep in mind, most of my time was spent planing the Cordura layout and then cutting and sewing on dozens and dozens of little pieces. If you could find a spandex that had a suitable texture, you could eliminate that part of the project all together.
