This is a vintage women's Niki-Lu turquoise nightgown with a built-in padded bra, hook and eye back closure, lace and yellow ribbon accents, and adjustable straps in a size XL.
It measures about 16" from underarm to underarm and 18" from the back of the neck to the bottom hem when laid flat.
The camisole is in pre-owned condition with a modification where half the padding was cut out of each bra.
