Why are womanly breasts round?
Answers: To fit into those round bras they get.
This is a simple answer.
well they would look pretty chance if they were squares...don't you reflect? I would have to influence it is because there is equal pressure man exerted on all areas. (If a woman is nude and laying on her spinal column, atmospheric pressure is the same on adjectives sides.) That's also why on old ladies, they are longer because gravity have exerted itself from the bottom until they have changed shape (skin stretches surrounded by response to gravity). Arms and legs are the shape they are because they have bones surrounded by them, in reality, all the body parts next to bones in them are given shape by the bone, otherwise they'd purely be shapeless blobs. Now, if you're asking why didn't boobs develop with bones within them to give them a different shape, I don't know.
Well, I guess it's only just the way God made them. It's matching thing as asking, "Why is the sky blue?". they are not round - every woman have different shaped breasts
some woman have close to tear shaped breasts ya know Mine are more resembling oblong balloons down to my knees-UGH!!
Most mammal flesh is shaped that path. You don't see square corners on anything other than those defined by bone. It would give the impression of being that the function of the female breast is resourcefully suited to the natural shape.
