Butterfly from Planetronika
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:
btrfly-planetronika, custom artstyle, short hair, orange hair, multicolored hair, orange eyes, butterfly hair ornament, blue top, crop top, halterneck, sleeveless, cleavage cutout, blue wristbands, grey cargo pants,
