I think her current gi is all about the American pride- Red, white, and blue with stars. Those kind of colours tend to stick with her cause she is one of the trinity of justice for America- like Superman, its about representing their country as much as the sex appeal. One thing I do on my characters is put them in thigh high boots- not only sexy, but practical for movement- I reckon she needs something to balance out the totally covered bottom though. I'd have to sit there and think about it a while. See, there's the American pride, and then the pracitcallity side. Baggy pants just look heavy on her...
No way- not on oekaki. I'd have to sit there and REALLY think about it. If I get time, i'll do it, but costume design is a weak spot for me as it is. It'd have to draw by hand. Oekaki is to weird to me still.
