Illustrious version works from -3 to 3+
I also recommend putting `large areolae` in negative prompt.
V2 should have less style and breast size impact especially when breast size is specified.
LORA weight: -3 to 4+
Trigger word: nipples
This is a slider, Lora, so you can choose whatever weight you want, so experiment and find what suits you best. A positive weight adds abs. You can use even higher weights such as 8 and above it all depends on characters and checkpoints.
