The goal was to make a plain white crop top that works on various breast sizes, keeps breasts looking natural, and passes the NSFW filter by not exposing breasts despite making them look very natural. May need to appeal after publishing, depending on your prompts and negatives. Recommended to add "exposed nipples", "exposed areolas", and "exposed breasts" to the negatives. Appeal usually not needed.
Tends to make breasts slightly larger and may add "bounce", but you can successfully prompt the breasts to be both smaller and larger. Usually makes breasts more natural even if large (aka not breast implants). If having issues with NSFW gens, add in "covered areolas".
Low weights have had variable success depending on the image style. Between 0.8-1 seems like sweet spot, but I've gone up to 2 without issue on some images.
Can change shirt color and breast size. Supports many angles. Can prompt many different necklines and shirt styles. Both loose and tight shirts supported.
May influence style to remove bangs, make hair brown, eyes blue, or skin very light. Can be used in combination with other LoRA to force these style aspects if wanted. Unlikely to generate wide hips or heavyset characters even if breasts are enlarged.
