Vintage women’s Jessica McClintock Gunne Sax black gown with slits & wrap 5/6

Women’s size 5/6 Pit to pit approximately 15” Length from shoulder to hem is 54.5” Simple and Chic black maxi dress with a v-neck, sleeveless design. Front has slits on each side and they are adorned with fabric covered buttons at the top of each slit. Beautiful piping gives provides extra detail and a flattering look. May be missing a hook and eye at top of zipper but I cannot be sure. Also came with a sheer black wrap which I will include. Unsure if it is original to the dress.
