80’s Vintage Beautiful Dress

This dress is absolutely gorgeous! I wish I could get the color right. It has a gray-ish blue background with pink flowers. It is fully lined with a high neckline. I believe it is polyester, no tag remains. Good used condition, no rips or stains. Either hand wash it or wash it in a lingerie bag in the washing machine. Measurements lying flat are about: L: 58” Armpit to armpit: 21”. It is hard to be accurate armpit to armpit since the material is stretchy.
