Nina Ricci vintage white lace nightgown bridal lingerie size 2 boudoir

This vintage Nina Ricci white long nightgown is in excellent condition. It features a loose short sleeve and deep plunging v neck and back. Has criss cross detail at the bust and button detail at the back. No flaws at all, excellent condition. Size 2. Approximate measurements in photos. There is no materials or care tag. The only tag on the gown is in the photos. The material feels like a polyester with a satin feel, but they is just my best opinion on the fabric type as there is no materials tag to confirm. There is no stretch.
