A couple of drapery studies, followed by a study of Rubens' 'Three Graces' (only two were drawn though!). As regards the drapery, I was being aware of the form underneath, while trying to understand the logic of the 'flow/fall' of the overlying drapery, and also how the thickness of the cloth influences both form and flow.
