It has accordion tulle along the back so I thought maybe it might be from the 50s, but what is it? Maybe a bridal bed jacket or something? It’s the oddest thing. It cinches at the arms with ribbon and also in the back. At the arms, it cinches on the inside of the arms, which I think is a little weird. It’s also very stiff, crispy and swishy sounding. I kind of regret getting it but it came in a lot. It also ties at the neck with a very unglamorous sort of cotton string instead of the blue ribbon it has elsewhere. What do you think? Thanks!
