So, I figured to give LoRA making a whirl and decided to create Gin. Unfortunately, though, I can only manage to get her normal clothes via the following tags:
black_skirt, brown_vest, puffy_short_sleeves, puffy_sleeves, pleated_skirt, white_shirt
Though there are images in her lora that have her Hero uniform, you may need to find a way to pull it out of her or make a new model for her with those in mind. Even with Version 2, I was only able to scrounge her Hero uniform up using "red jacket" and hoping it would summon it, but I didn't do any special keyword making for her Hero form specifically.
