because of a couple of issues. First the zipper, but I'm over that. I took out the hand-stitching, undid the lining, and did more of an invisible zipper app with stitching much closer to the teeth. I didn't have the stamina to undo the whole thing and apply interfacing, but you can bet next year I will if I make another dress! Thank you ladies for that tip.
No, the depression came after I saw that the back lining rolls out, which I think I can fix by tightening that up inside, and if I can't, then it'll just be a design element to show off my pretty blue lining!
