After a user complained about my first breast size slider, I naturally deleted it for the benefit of the community.

So here's a slider with different training settings.

The slider delivers good results with weights from -3 to 3.

At a weight of -6, only the nipple remains visible, and at a weight of 4, the nipples swell too much and look artificial. Therefore, I recommend using weights from -3 to 3. Whether the person is naked or clothed is irrelevant. It also works well with other LoRA (e.g., character LoRA) without altering the character's physique or appearance.

With other sliders, I've noticed that increasing breast size automatically increases body fat or simply makes the face appear fuller.
