It seems that every time that I insert an invisible zipper in a dress that needs a lining, the top of the zipper ends up pulling in towards the inside of the dress (pulling the top of the dress with it). I thought that it was the bemberg lining that I was using, but it happened again with a costume that I sewed using a cheaper, polyester lining. We’re going to be wearing our hair up with this costume, so I need the zipper to look good. Any help would be greatly appreciated.
