This is a sensational 1980's iridescent silk chiffon vintage Bill Blass dress. It has asymmetrical ruffles that fall from the left shoulder to the floor. It is lined in a flesh/peach and has a tan chiffon overlay.
This dress has wonderful angel sleeves and a back zipper closure. It is approximately a US women's size 10/12, but I encourage you to use the measurements as a guide for the best fit.
LENGTH from nape of neck: 60"
