Lol, yes you did, otherwise you wouldn't have included the rhetorical question at all and just said it as a statement.
Putting that aside, however, after watching a few more videos (purely for academic reasons of course) I have a new theory that explains why there's so much uncertainty, because even if that marginally qualifies as retrousse, you absolutely can achieve it with today's breast augmentation methods.
I think they're 1 and 1
To better show why I think this way we need to first establish sides of her body. Left and right are meaningless when images and videos can easily be mirrored for one reason or another.
For our purposes, I'm going with beauty mark side vs non beauty mark side.
Beauty mark side has a beauty mark right above the corner of the mouth, a mark on the inner side of the nipple, and another on the inner/top area of her thigh.
Non-beauty mark side still has a few marks but not as many. One on the arm right near the tit.
They both have one on the inner upper part of the tits, but the "non" side's mark is higher up.
I think the beauty mark side is the fake tit side and the non side is the natural side. Looking at the images below it's easy to see which side is which and why I think at best it's 1 and 1. One side lays flatter, one more bulbous. One side creates flat straight sections while the other doesn't. Even in the image where she's bending over one side stays round while the other kind of bananas out.



There are, obviously, many reasons to only get an implant on one side, but don't really need to know the 'why' of it.
