The suit of the combat cyborgs known as the Numbers, from Nanoha StrikerS. With the right prompting, clothing combinations that have the suit underneath can be made.
V2: Should have much better suit consistency. This consistency only applies to using this model alone, putting it with other models may lose the two-tone pattern. Be prepared to put "F" in negative prompt (if you don't want it there), a good amount of the training data had that engraved on the neckplate (because Fate).
