Definitely practice drawing some female figures. Back when I was still drawing, the hips would start out as a triangle pointing up, meeting the triangle pointing down that forms the shoulders and torso. And I'd try to draw the little butterfly shape of the pelvis over that so I'd get an idea of how to form the hips and legs on top of that...
I'm sorry, I'm not much of an artist anymore, I wish I could offer more help than that
