When I tested this with different checkpoints and LoRAs, it seemed to work quite well.

A LoRA weight of 0.8 works great, though you can adjust the strength as you prefer.

Prompts I usually used:

long dress, purple dress, long sleeves, long cape, black cape, green hair, low ponytail, gold bracelet, blue eyes, purple forehead jewel, yellow waist sash,

SD 1.5:

A LoRA weight of 0.7 works great, though you can adjust the strength as you prefer.
