It almost looks like the lace doesn't match all the way through? I am asking because I wonder if the skirt is actually old, like c. 1905, but perhaps relined, and the top was made up to go with it? Usually lace is matched . As is, it strikes me as late 70s because of the Bishop sleeves, which were popular then, but its hard to tell without handling and seeing close-ups.
I see 1970s in this lovely dress. But without seeing close ups of the details and knowing the fabric, it is difficult to be sure. It is, to me, a step above the majority of 1970s wedding gowns one usually sees.
Thank you all so much for the responses! I confirmed that the material is embroidered/lace netting and matches top to bottom. The bottom layer is very shiny, soft satin, with a lace edge. The back closes with a zipper. The zipper is plastic, but the pull tab is metal with no markings. Six (6) fabric covered button closures on each sleeve. Hook closure at neck. Most seams are serged.
