Create a reference sheet with an emphasis on the character's clothing. You don't need to provide too much tags beyond the triggers (reference_sheet, clothing_reference, english text, multiple views), but the more clothing triggers you provide the more complete the image will be; check the example images' prompts for reference. It works apparently well for characters already baked in the checkpoint (I tested on WAI v12.0).The LORA weight works fine around 0.7 and up to 1.0. I didn't really test below it.
