I was tired of other LoRAs without the areolas textures and details. Most of the nipples I got until now using Flux was some soulless plain areolas without the depth it requires.
Then I curated a mid-size dataset with the best breasts and areolas I could find today in the internet.
Flux does what it wants LOL. I trained different concepts, but flux does not follow them as it did with SDXL. Flux seems doing a breast based on the overall girl appearance, but it's possible to achieve using inpainting and some prompt engineering.
Trigger words (in red, but not required at all) that "may" have some effect when inpainting and guided are below. If they don't work no problem, it's just Flux trying to use the best nipple to fit the girl.
big areolas - Rounded medium to big areola size
dark nipples - Dark nipples with more contrast to the natural skin
ghost nipples - Pale nipples that appears slightly
ginger nipples - Nipples from the Redheads
long nipples - Nipples that you can bite easily
regular nipples - Normal regular nipples and areolas. In doubt? start here!
saggy breasts - breasts hanging a bit due to the gravity
small areolas - Areolas with a small radius
veiny areolas - Veins appearing under the skin (Flux does not like reproducing this one...)
Bonus that I added in case the full body appears, to have something right down there:
hairy ***** - hairy ***** of a woman standing
shaved ***** - shaved ***** of a woman standing
You can combine more than one. Inpainting them to improve the result is a good option.
Use a strenght from 0.7 to 1.5, depending on your scenario. Negative weight put clothes LOL
