Breast shape
From Voyeurweb's Wiki about Sex
Breast shape describes the shape of the tits of a woman, very often by trying to use analogies from other objects. Talking in terms of shapes, a breast can be described as a cone, which tapers from the circular base of her tits to one point, which would be her nipples. Of course a breast never translates into a mathematical cone. because it does not have a rotational symmetry. The most important parameters to determine the shape of a breast are: The ratio of the tit length versus the tit base line and the horizontal tit angle.
