Illustrious usage and notes:

• Positive prompt: jill valentine, 1girl, short hair, brown hair, blue eyes, breasts, tube top, bare shoulders, skirt, clothes around waist, boots

• I suggest using the above tags as starting points and change them accordingly by removing tags you don't need. Most of them aren't actually needed.

• If you want, or do not want, the tactical gear version of her outfit, then add this to the positive or negative prompt: suspenders, utility belt
