Black sexy dress Medium

This Marian & Maral little black dress is a size Medium. Poly and 8% Spandex. This dress was lovingly worn by my daughter, and she is ready to let it go. Clearly, the Spandex offers a lot of "give," but here are the measurements: 14" armmpit to armpit 5" drop U-shape neckline 24" armpit to hem. This is a dress for a night out of any variety! Feels great!
