Try size: 512 x 768 or 768 x 1024
Sampling steps: 10~20 (Too high might make the nipples appear larger.)
Distilled CFG Scale: 2.5~3.5 (The higher this value is, the higher the weight of Lora should be so that the style can be stable.)
Weights: 1
Note: It's not a slider tool, so don't expect too much. And I think flux is too random, and it takes luck to generate an ideal picture. Whether breast shape is good-looking or not is very subjective, so just appreciate it with a relaxed attitude. (FLUX)
The following is the teardrop milk analysis given to me by ChatGPT 4o: "An E cup (approximately equivalent to EU 75E or US 32DD) is the aesthetic upper limit for teardrop-shaped breasts, and usually requires the support of implants to maintain the shape." "Beyond an F cup, maintaining a teardrop shape becomes extremely difficult, often resulting in a bell-shaped breast. Beyond a G cup, it becomes largely unrealistic, as breasts tend to become pendulous in form." “Teardrop-shaped breasts beyond a G cup are structurally implausible and aesthetically inconsistent with the natural form, unless heavily supported by surgical or external means.”
