Late 60s early 70s Full Length Black Sequined Gown w Side Thigh Slit

This dress is absolutely stunning. Circa late 60s, early 70s it’s a full length long sleeved black sequined gown. It has a high thigh slit and a high rounded neckline. It zips up the back with a metal zipper and is fully lined satin. In very good vintage condition - no major flaws to note. All sequins appear to be intact - but with a vintage gown it is possible for one or two to be wobbly or missing. No size tag - see measurements in photos. Approximately a medium. Would be a perfect NYE dress!
