I modified the original design for this lacing detail at the coat back.

Coat Front when worn with the sheer dress.

Shows how I boned the coat along each side of the center back.  The steel bones are shown superimposed on the boning channel tape I stitched in place before pleating the back.  In this position, the steel bones are encased in the fold of each pleat and then top-stitched. 

Placing ribbon loops over each boned pleat through which to lace 1-1/2"ribbon.

Coat with hand-basting still in place over the seams.  The faux fur collar is detachable for times I wear the coat without the sheer wool dress (dress separately reviewed) since the dress Ascot takes the place of an ordinary collar.
