Because it's more fun to be the bad guy.
I'm a huge Sailor Moon fanatic, and after realizing my dream to cosplay one of the Sailor Senshi, well, it was time to turn to the dark side. It's hard to pick favorite villains out of the Sailor Moon anime, because they're all so delightfully ridiculous, but Mimete absolutely ranks up there. Her design was pretty challenging - gravity defying hair, ruffly skirt, and a completely ridiculous prop. (That, I can't take credit for. Justin, my partner-in-crime, made it from PVC.)
New innovations for this costume included: using horsehair braid to achieve A THOUSAND RUFFLES, a method for painting tights that actually looks good (and painting while wearing them, no less), and finally discovering a good way to curl a wig.
