Put on negative all acessories and clothes that you don't want like "school uniform, coat, skirt, hair ornaments, maid headdress" and etc... (these appear frequently),
For train i used few and low quality images i found from her, so don't wait for much.
I liked the character so i tried to do a lora for her :)
I'm really new making that stuff so the lora is probably much simple, but I highly accept advices...really.
If i keep going well i will try to create other loras for the very niche characters that i like.
