This app can guide you how to draw easy female bodiesexample step by stepHere is another pose, showing the torso from a front view. Note how the breasts are still located at 45 degree angles from the center line of the body. Oh, also take note of the shading. After looking at various examples, I find that shading in this fashion (rather than just following the lower curves as you would shade a sphere) makes them look more natural. Here is one last pose to go over the size and placement. It's harder to see here, but the breasts are still at the 45 degree angle from the center line (which isn't drawn in this picture; sorry about that). Notice that the leftmost breast is drawn as a half-sphere, not as a full sphere. If you want to exaggerate the size, that's your choice, but I personally don't think its necessary.
