Black silk crepe sleeveless cross heart dress with empire waist

Black crepe sleeveless cross heart dress with empire waist that ties up with a ribbon. Adjustable ribbon straps on shoulders. Hidden zipper on the side. Flowy silk crepe fabric. Vero Moda brand. Size 34. Feels like a X-Small. I am a size small with 32 D bust and it feels a little bit too tight, it was fastidious to zip! *one button is missing at the shoulder.
