FWIW there's a subreddit community dedicated to "ideal" breast shape, which they explain in a pinned post: https://old.reddit.com/r/fortyfivefiftyfive/comments/ark20j/... (NSFW; the community is for porn and the top of the is full of their favorite images). The pinned post cites another study.
It looks like you're trying to evaluate the importance of a lot more details than that, and I'd be shocked if you weren't already aware of that study, but there it is just in case.
Thank you very much for your interest and support!
In deed we were already aware of this study.
However we want to get a far more profound understanding of the influence different parameters have on the breast. The study is designed in a way, that the most important parameters around breast (reconstruction) surgery (e.g. breast size, breast shape, areola size, areola position, scars etc.) are being combined in 88 images in a way that in the end allows us to extract the data "broken down" to the different parameters. So results of the study will be something like: in case of an areola size asymmetry, more people tend to accept the asymmetry then a size correction when you therefore have scars. I hope that explanation helps a little bit! Thank you very much again for your support!
