True Vintage Powder Blue Pegnoir Nightgown

Powder or sky blue with white trim details and a little lace detail on the chest Pegnoir nightgown It has a tag but it’s so faded I can’t read it. It’s definitely nylon and definitely vintage, I would guess 60s. Very pretty and has stretch to it, as you can see I can get it on my medium/large dress form. However, I believe it is best suited for a size small or smaller medium. It comes with a ribbon to tie at the waist which I will mail with it, but it is supposed to be fed through the waist. For picture efficiency, I just tied it around the outside. The ribbon is also blue. It’s super cute, just doesn’t fit me.
