Vintage Daygown

My MIL found this and a few other vintage items in storage. This was worn by her sons in the late 70’s and early 80’s. No branding or sizing tag on this daygown. Would recommend for NB to 3 months. For being kept in storage for so long, I could find no discoloration whatsoever. The yellow is a soft pale color, and the material is very lightweight and thin, almost see-through. Very delicate. Has an adorable cowboy embroidered on the front, and some detailed embroidery on the collar. Buttons up the front. I found two flaws: there is a brown mark on the collar and two small holes in the fabric near the bottom of the gown. See close-up pics. I have not tried to treat the brown spot, so it may come out. Also, the holes go through the front and back of the dress, almost as if a needle was threaded all the way through.
