This is a beautiful little piece. I believe it’s from the 1930s. I apologize, as I really don’t know. It’s made of a light cotton material very soft a bit sheer. Can be worn as a dress or slip. I would say about a size 8. I’m a 5 foot five gal with a 34C bust…fits me… I’d say a size 8. Slips overhead. Pretty little lace detailing with tiny glittery blue black beads in the lace. This would look cool with combat boots or sexy high heels. Last photo, not mine, but a cool way to style it!Sexy Boudoir Evening Funky Bohemian Delicate Dressy
