*Note: The trigger word contains 'loli'. If you encounter a generation error, please change it to 'little girl' or something similar.
When using LoRA, it might be best to use LoRA 'DMD2' in conjunction with it, and generate the sample with Sampling Steps around 10 and CFG scale between 1.1 and 1.3 (other advanced settings can be left at their defaults).
Adding a long skirt to the prompt will improve the accuracy of the costume reproduction. Also, just to be safe, you might want to add "1girl" after the character name in the prompt.
