The Sickle Rigging and Morphing System. This shows a little of what you can do getting morphs from the bodysuit (the dress with handles is in progress right now, and the boot/shoe conformers will be last). The left is autoconform to Genesis, and the right image shows autoconform to the System bodysuit. The suit is tweaked and adjusted to minimize distortion in the waistline and strap areas as well as the more obvious breast deformation.
Shown with DAZ Genesis V5 Supermodel. Clothing meshes are mine.
