Vintage polyester floral dress

Beautiful and dainty gemstone / navy blue vintage dress. Worn once and in excellent condition. Zips up in the back. Spaghetti straps. Has a two-piece look but it is connected. There is no tag / size. The tag shown in the photo was sewn on by the vintage shop from which I bought the dress. I’m a size small / 2-4 and it fits comfortably. Tags: purple, magenta, pink, green, orange, navy, blue
