Asymmetric: One breast is larger than the other; ranges from minor (barely noticeable) to more pronounced (as pictured).
Bell Shape: Generally heavier breasts; narrower at the top, then drastically fuller toward the bottom.
East West: A gentle slope from top to bottom, but out to the sides; nipples point in opposite directions.
Side Set: A wide space in between the two breasts; nipples point a little more forward than East West.
Slender: A little wider at the top, narrower at the bottom; generally skinny without a lot of breast tissue.
Tear Drop: Similar to Bell Shape but with a much gentler slope; easily identifiable from the side.
Round: Equally full on top and bottom; often surgically enhanced, but not always.
