Vintage 60s Rontini grey and taupe button down mod midi dress, 12 or xs-small

Vintage 60s Rontini grey and taupe button down mod midi dress, size xs to small A line silhouette with bulbous buttons and a nice weight to material. Size states 12, but that is a small waist, so I would say closer to xs-small. Union made in the USA, no pockets and not much for stretch.
