This is a gorgeous piece! I believe it was meant to be a nightgown but by today's standards it could easily be worn as a Summer dress. Made of soft yellow cotton. The straps, neckline and waist are made of wide beige eyelet lace. Shirred bustline. It closes in the back with small buttons. Slightly full skirt. I photographed it with a petitcoat underneath (not included). This is flawless. Best fit would be a Medium, however, please see the measurements below for a proper fit.
