Women with wider shoulders and narrower hips (reverse triangle shape) tend to have larger breast so if you saw that in a woman's skeleton you could assume she had big fat titties. On the flip-side, women with larger hips (pears or triangles) tend to have large butts and smaller breasts.
Women with narrow, equal proportions (straight) will have both areas as small and women with exaggerated, equal proportions (hour glass) have the best of both worlds but those skeletons could also be apples which store fat in the torso.
