All right, I think I found a Supergirl costume in XS that will fit... suitable for a f**hag of the Asian-Persuasion that is me...
(Does that make me an honorary Gaysian?)
We'll be a sight... Wonder Woman and Supergirl riding down the street, capes flying, singing a jaunty tune. I'm thinking the theme song from the old Hercules cartoon would be appropriate...

"Hercules...softness in his eyes,
Iron in his thighs,
Virtue in his heart,
Fire in every part...
of mighty Hercules!"

P.S. I hope we don't get shot.
