Plum Line

I'm currently having issues with how I draw fashion illustrations. I've only recently taken to respecting the plum line because my technique for years was to draw the outside in, having never been trained formally in anatomy. But I also have difficulty drawing from anatomy, because I tend to be slavish to the form if I draw it as a croquis first, and that sometimes gets in the way of how I render the clothing.

This is my current default walking runway pose. I think it's derived from a drawing by Lamont O'Neal, but it has all the contraposto jauntiness I look for in a runway pose
