Shinju Inui - My Dress-Up Darling
Keep in mind that settings may vary slightly between different versions. See below for more details.
When I tested this with different checkpoints and LoRAs, it seemed to work quite well.
Illustrious:
A LoRA weight of 0.9 works great, though you can adjust the strength as you prefer.
Prompts I usually used:
shinju_inui, pink hair, long hair, hair between eyes, pink eyes, light blue shirt, loose sleeves, short sleeves, wide sleeves, white skirt,
