This is a requested character LORA metioned in comment! Thank you all for reviews and feedback!
Celia Claire from Seirei Gensouki! It was trained on NAI with anime images so it may not work well with realistic models.
Suggested weights: 1.0 for anime based models
Trigger words: 1girl, celia claire
To trigger the outfit: white capelet
Tips: put epaulettes in negative prompts! I'm not sure but it looks like the lora was misled by the red ribbon on shoulder part.
