The apron is fixed waist and closes with buttons and hooks, with the waist tie threaded through the back of the removable bow. The apron portion and tie tails are lined in white cotton, straps are self-lined.
The skirt is a gathered flare with a hem circumference of about 125". I cut the skirt on the cross grain so it wouldn't have extra seams from gores. The lining was cut in six gores to avoid having the side seams on the bias, where the weight of the ruffle would pull it completely out of shape. When I do skirt linings with attached ruffles like this I put the lining in "backward" (seam allowances facing in toward the legs rather than facing out, with a french seam finishing the seam at the zipper) because the outward-facing side of the lining tends to show a bit with movement.
(There are 525 inches of pleated ruffle in this dress and apron. And since it's box pleated, I couldn't just fork pleat it. I hunkered down at the coffee table with my ruler, pins, and chalk and some Poldark and did some intensive pleating.)
