I threw more than 200 images into the blender for this clothing Lora. What the images have in common is a smooth chest-silhouette. The aim is to avoid "nipple poking". I hope it will help produce smooth clothing over the breasts. The image collection included a variety of clothes, with and without cleavage.

update: early returns suggest that either: I have no idea what I'm doing; or checkpoints overpower clothing Lora. I will keep experimenting, but for now my initial conclusion is that the Lora doesn't perform as it should.
