Burstinatrix
helmet, bodysuit, gloves, thighhighs
face paint (if necessary)
put "greyscale" in negative prompt
Idk why, but sometimes seems to generate black/white on specific models. Maybe cause her skin is already grey & all the dataset images looked pretty similar. Also wasn't much variety with clothes in dataset, putting the outfit triggers in negative might help if you want something else.
