This is a cool slip from the 1960s, very vintage. The condition is like new, it looks to have never been worn. The slip is a wrap styling, I guess to have expansion room at the hip when you sit down. It is fashion of nylon and has a garment workers label. No other label is present. It is size JR 9-11. Waistline is up to 26", length is 13-1/2".
