Prompt: wearing a slavekini - More flexible to the character you are putting it on, will change colors more willingly (i.e red slavekini) and their hair shouldn't have the hair ornament. May have to add pelvic curtain if you want that.
Prompt: wearing a slave leia outfit - Natural token built into SDXL that has also been trained into this lora - very willing to reproduce the outfit including the braid, hair ornament, makeup, pelvic curtain, armlet, bracelet, brown hair, cleavage without prompting for it. These can also be prompted away in the negative prompt, albeit a bit harder to get rid of.
This model is less willing to go topless but it should work if you remove the prompt: slavekinior slave leia outfit. bottomless seems impossible despite having been trained on it, good luck.
