WOW, fantastic Lora!!! I have never seen any lora like this. It is inadvertently taking into account a woman's a base height and inframammary fold using empirical body proportions. I am trying to state that the breast anatomy and position on the body is entirely accurate and have a direct correlation to human biology. If anything, these are the most accurately displayed breasts from flux I have ever seen. Five stars and a tip

Educational breast PSA for anyone that cares:

The breasts posted in the gallery are quite low due to natural formation. The "low breast" is something called a base breast height. It is the measurement from between the clavicle down to the natural under bust line. This base breast height helps in bra sizing and is indicative of breast height. Ergo, how high or low a woman's breasts are is based on this primary measurement and plays a direct role on how high or low she would need to wear a bra. Even if we compare AA cups. One woman may have a high base breast height and another may have a much lower chest (like this Lora). So this is entirely irrespective of bra size or breast volume. A typical base breast height is around 8.3cm. Breasts always sit atop the pectoralis major muscle, so it is impossible to have breast tissue beginning at an ultra-low point of say 16cm (halfway down the rib cage).

The second metric this Lora is unwittingly taking into account is the inframammary fold, also known as the IMF measurement. This is the natural crease the breast makes when viewed from the side. The IMF measurement is taken sideways, from the top of the arm down to the beginning of the crease. The IMF typically has a direct correlation to the under bust measurement. While the IMF is not the highest most start of breast tissue, it tends to mark the lowest point of the pectoralis major muscle attachment to the breast. If a woman has a natural low base breast height, then she also has a larger/lower IMF measurement.

Miosotis is a great example. She has a naturally high base breast height, but her breasts are past her stomach. So one would presume she has a very low IMF due to hanging breasts, but this is not the case. She has a very small IMF and this is because the growth of her breasts developed much later past puberty. That is empirical science.

The underside crease of the breast is also part of the inframammary fold as it denotes the lowest attachment point of the breast to the body itself, as seen in the linked photo.
