See my examples for prompting style. Just use natural language. No specific keyword but words like nipples, breasts, and topless work. The samples were generated with LoRA strength 0.8. I find it helps to give random names, especially if you want multiple people. I've been sampling with guidance 3.0, simple euler schedule with 40 steps. I was using with max_shift and base_shift 0 but other values work well. It is trained with the full precision t5/clip conditioning so it will work best with those. Feedback welcome.
