Theres already a couple of princess peach LORAs but the one I liked wasnt very flexible for what I wanted so I made my own. Its hit or miss depending on the model but you can try testing it out. I wanted her official look got what I wanted out of it. Lower the weights if having trouble. It should be able to do NSFW. Ironically enough it works well with yiffymix. Just use furry tags in negatives.
Use Princess peach, blue eyes, blonde hair, earrings and crown.
She has long hair or ponytail for your preference.
May come back to this one
EDIT: been sitting on this one but with SD updates my Model works much better and works on more anime/cartoon models
