Silk nightgown or slip dress with floral embroidery

Soft black nightgown or dress with embroidered flowers along the neckline. Scalloped neckline, armholes and hem (see photo—some fraying on the hem). Google translate says it is 100% silk. No size tag (that I am able to read at least!). Bust is about 18”, Length is 36”. Hips and waist are free. It looks like the previous owner has shortened the straps, but no fabric has been removed so that could be taken out. Very pretty and feminine!
