This is another one that I was going to keep for myself, but I'm sharing it because the outfit is hot. I only had 3 reference images so I had to create a miracle to have it work.

First, depending on your setup you might need to adjust the weight from 0.7-1. You can go lower but then the outfit starts failing.

Second, I would put detached sleeves on your negative prompt.

Third, the reference images had the girl with her hands adjusting her clothes so it tends to sometimes default to that pose. Sort of how Futaba looks in the second pic in the post. So you might want to prompt what her arms are doing to avoid this if the character is solo.

So something like arms at side, hands on own hips, hands on own knees, hands holding object etc etc.
