If you can't find a pic you're happy with, you can just describe the outfit in text.

Aince I dunno what your character's powers or personality is, giving suggestions for specific images is a bit hard.

But when I was looking for my won hero costume, I just went to my local anime-art website and typed in some tags I wanted, like "bodysuit" and "blonde_hair". And then i got some pics of Sue Storm from Fantastic Four, but in anime-form. So, yay?
