Sienna, aka the Red Canary from DC Comics.

Triggers: redcanary, black hair, black eyes, fingerless gloves, fishnets, pantyhose, leotard, red jacket, torn clothes, mask

I had trouble with generating her without her mask, probably since there were only a couple of images of her not wearing it. Using different prompts, negatives, and turning down the strength helped, but I think if you have her in costume, her mask is gonna have to be on.
