Vintage 1950’s on sale cotton lawn and lace Victorian style nightdress med

Lovely nightdress, I've had to do a bit of speculation on this nightdress. It came with a lot of Swiss sheets and handkerchiefs and it feels like a good quality Swiss lawn fabric edged with cotton lace. I think it's on sale 50's but it could be earlier. The machine stitching is excellent with french seems and tiny machine stitching. Altogether a beautifully made quality nightdress which looks unworn.
