Vintage dark indigo dress size 6

This dress belonged to my mother! Size 6, probably fits close to a size 4. Color is a dark indigo, maybe slightly more purple than blue. Material is polyester and spandex, very soft! Sadly, I no longer fit in this dress! There are just a couple of tiny stain spots around the neckline. I’ve never tried to get them out so you may be able to. I have it pictured.
