You know, when someone comes to the site and says...
"Which surgeon will give me the best, most natural looking, 102% passable (with a 2% margin of error) vagina?"
...we send them to the Great Wall of Vagina (seriously, look it up) and we ask them which was the perfect one?
I would say that the same will apply to breasts. In fact I looked before I made this post. Not all breasts are big, they're not all round, and most are a bit unequal. 🙂
