A beautiful body shape needs to follow a beautiful line of action that curves and flows with grace. Draw the red line, the line of action, lightly as we will erase it later. Draw the head, and ellipses for her upper and lower torso. Notice they are nearly the same width, but that where the shoulders will be drawn in a little wider than where her waist will be drawn. Many people think they should draw a wider waist , but in a model's proportions, women have wider shoulders than waists.
