Model of Sebastian Sallow from videogame Hogwarts Legacy.
Trained on various aspect ratios including 1:1, 7:9 (≈3:4) and 13:19 (≈2:3) and also a few horizontal ones, but probably works best on portrait ratios.
It can generate original Hogwarts school robes or any other kinds of clothing. Use keywords "wearing black wizard robe with (color) collar, white shirt and (color) striped necktie" for generating that. I recommend using it with the original Flux dev checkpoint, but for some realism Flux dev fine-tunes it works fine too.
