Works well at Lora value 0.7-1.0
Trained on a variety of breasts shapes.
Tested at 0.8 with the GGUF FLUX Q-4_0 model
Tested with Saggy Breast, and small breasts, large shapes seem to have been learned at a greater level.
NOTE: It has been reported that "1girl" can produce problematic images. I have not had an issue with using female or woman in onsite generation.
