loRA of Sachiko Juraku from Kakegurui Twin
For completely canonical clothing use loRA at 1 or 0.6 (which I highly recommend) but using the additional prompt "black necktie"

Also, I have long plagued with hair color, in this version with such a problem has not encountered, if the color of the eyes is not so bright or hair color you do not like, in general, in any unclear situation you are free to add "Sachiko" in the prompt
