This was a gift to me from a few years back I recently found moving. I’m not 100# on authenticity bc it was a gift, I do not have the Dior box it came in or the serial # on the receipt… This bathing suit is sexy either way! It’s all black, with the name “Dior” graphically printed on horizontally. It’s a size medium, but anything made in Italy, France Etc… always runs on smaller size. It’s 14.5” across And 25” in length. It obviously has some stretch and a deep scoop open back. Would be amazing solo on the beach, or worn as a body suit! And there are removable pads. Def open to offers! This looks so friggin cute w/white mini, Denim mini and or even just a pair of shorts!!
