USE "REALISTIC" in negative, if you want pure anime.
I had to add some realistic images in my dataset, to get enough proper images, so if you don't add it to negative, you might get some realistic/semi-realistic stuff unprompted
Limited dataset, but I think it works quite well.
A weight of ~1.0 is recommended (You might want to adjust the weight depending on your model). Feel free to experiment with other weights and share your results if you want to!
The main prompt is "off-shoulder bikini".
You should be able to change color like this: "off-shoulder bikini, [insert color] bikini"
Let me know if you have any issues.
