Bottom left of the thumbnail gallery. It's the same design as the TRON Legacy. At first you think it's just a spandex or similar clothing. But yeah, *cough* way too tight. Probably a flesh suit, but having seen some of those worn up close with friends in the industry, hers has to be fit incredibly well, or there isn't one.
And yeah, the blood elf girl = win.
Looking at these are fun and gives me an incentive to get in shape for next summer con season.
