No brand strapless cover up dress size medium

Super cute strapless cover up dress. Such a great dress can be worn alone or over a bathing suit. Has a layer of material inside for coverage. Also feels nice to. Not sure what is made of but I think it might be polyester. It's feels soft yet slick. I would say it's about a medium in size. There's no tag so I don't know the brand either. Worn a few times but still in great condition. No stains rips or tears. From a smoke free home.
