Tips to use:
Use LoRA weight between 0.6-0.8
For her original outfit use the tags: pikkyshikimori, 1girl, solo, looking at viewer, pink hair, long hair, bangs, hair between eyes, blue eyes, breasts, medium breasts, shirt, white shirt, collared shirt, school uniform, sweat, jacket, blush
These prompts are all tags related to her original outfit, If you use these you will get a pretty accurate result. You can omit some stuff, but I wanted to give all possible tags
