well there are many social/personal factors. I still consider aloegoddess and L.D. Mackenzie to be bigger losses than E.B. here. EB started with G cups, not like these two predecessors at J-cup range. Mady Gio, a current model, also owns G cups. Rachel Raxxx also once owned huge, not just big, tits.
If I don't count Merilyn for a separate (actual sickness) reason, only LDM and RR above *returned* to modelling, and we already knew how audience thought of them, BR and then implants.
Really, BR is a personal decision. Do it, and don't come back. No tits guarantee a woman any long term job. Hitomi and Katerina are almost retiring. Women get replaced by women, I am sorry to say. Someone does BR? Then that someone gets replaced sooner.
This discussion will just die out fast since the protagonist has also "reduced" her career. There really are so many busty models, even if not all own J cups or above, on IG alone, not to mention OF. I concur with the view that models, BR or not, need to know OF is not as a sustainable business model as they thought. I wish professional photographers and bigger producers will enlist more girls and ideally pay them better.
