I have inserted the invisible zipper and sewn the side seams. Lining was completed first and glad I did it that way as I ended up taking 1 1/4 inch seam for the zipper in the upper back area, tapering to 5/8 just above the waist to zipper stop. I really have a narrow upper back. I also shortened the back bodice by 5/8 inch from center back tapering to nothing at side seam. I also sewed longer back waist darts to get a better fit.
In addition I sewed 1 inch seams at skirt bottom tapering to 5/8 from waist up. I have yet to try on the dress after sewing. Hopefully these adjustments are enough.
Here is a photo of the center back seam with zipper inserted.
That's all the progress at this time.
