Turned out quite well overall, I could probably put it through a few more epochs. Maybe I will, but for now it's good enough.

Tags to use:

yoosoojin, 1girl, medium hair

For clothing and other appearance:

glasses, school uniform, capelet, collared shirt, short necktie, high-waist skirt, pantyhose

There was supposed to be "black footwear" tag for the shoes, but it was just one image, so it didn't learn it at all.

Base style is affected a bit, put "lips" in negative if you want a closer to original look.
