Vintage Shadowline Petite Nightgown/Robe Peignoir

It is hard to pinpoint when this was made. There is also a lovely embroidery on it. The tag says petite so I am guessing it is a size between 00-4? There is a comfortable little elastic band to give you a little waist. There are two layers for the robe and a solid layer and sheer layer for the nightgown.
