I just got this from Zulily and they don't take returns. It definitely does NOT fit a size 16 40DD cup size. I'd say it is more like a Large (14) maybe C cup size. It didn't come with tags and I don't see Cupshe name on the suit tag. This tankini set has mix-and-match appeal with added coverage for sunny-day style. - Includes green and white floral tankini top and black bikini bottoms (two pieces total) - V-neck - Tie back - Full coverage - 80% nylon / 20% spandex - Hand wash - Imported
