Garment Blocks

This is an idea from my Sketchbook (visual diary), from at least 3-4 years ago.  I believe I found it in a forecast magazine of that time (Textile View).  The design is elegant but may have some inherent problems to be dealt with in the first toile/prototype.   Your fabric choice will be important as the ruching suggests much of this skirt will be cut on the bias and there may be a little tension between the ruching around the thighs and the flare I have drawn into the hem.  I'm also concerned that the gathered hip yoke could be puffy if not sewn well.  I would probably work with a light-weight, finely woven wool suiting as I know from experience that it behaves well when cut on the bias.
