Hiya Papaya,
Normally I don't do LoRas for characters that already exist but the ones I saw didn't support any outfits.(Or at least didn't show that they did) So here we are. This model currently supports her original outfit and the one she wears around the house. Again this uses anime screenshots so retro_artstyle should have some effect.
Putting the outfits in the negative might help if the outfits are too strong but I didn't have a ton of trouble with it in my test.
PS.
