Tips to use:
Use LoRA weight between 0.6-0.8
For her original outfit use the tags: pikkykaname, 1girl, solo, looking at viewer, purple hair, twintails, short hair, hair between eyes, ponytail, short twintails, blue eyes, breasts, small breasts, hair ornament, ribbon, school uniform, apron, serafuku, hairclip, long sleeves
Theese prompts are all tags related to her original outfit, If you use theese you will get a pretty accurate result. You can omit some stuff, but I wanted to give all possible tags
