Antique sheer boudoir robe with ruffle lace at neck. The main body is in a midnight shade and sheer texture feels almost like pineapple fiber fabric with a slight crispness to it. Likely a cotton organza, but there are no labels so these are our best guesses. The black lace work gathers at the neck and makes for peekaboo sleeves.
