Sorry for fizzling out on the "whole week" of WW; my day job and book production got in the way.
Long story short on Wondergirl: she originally appeared in the pages of WW's comic as simply WW as a girl (in non-continuity stories). The editors of the Teen Titans series was asleep at the wheel and made her a member (in continuity stories), creating a long history of trying to explain her existance.
My drawing is after Gil Kane's famous revamp of her in the early '70s. Her costume was a marvelous blend of practical (pants! no cleavage on display! low-heeled boots!) and impractical (magic lasso as her belt! necklace and medallion! and matching wrist bracelet—not pictured). I love the field of gold, silver, and black stars wrapping around her body.
I had drawn a similar one for a fan @ NYCC which turned out horribly, so I had to do it right. Looks like I need another silver star on her hip though.
I'll also use this when I re-make my packaging for my custom Mego Wondergirl. If you're not familiar with Mego action figures, or the fervor for customizing them, I really can't get into that here and now. It would probably require a whole blog devoted to it.
