I just purchased this vintage Dior slip which the seller listed as size Medium.. but the inner tag says Large, which is really too big for me. By the time I picked up the package and discovered the error it was too late for a refund so I will reposh and hopefully this will find a good home. This can easily fit a size Medium depending how tight you like the fit. It really is an amazing piece.. in a Tiffany pale blue with hint of green. A real treasure. If you have any questions or need measurements lmk. Offers welcome!
