70s maxi skirt. No tags. I think the fabric is Lurex because it has sparkly metallic gold threading throughout an abstract fabric of black, muted gold, green, blue, red, and purple. Fabric is lightweight and has stretch. Measurements are approximate and taken while laying flat: the larger skirt has a wide elastic waist that measures anywhere from 11inches relaxed to 15inches without much resistance 18.5 inches across the hip and 40 inches long. There is a 21.5 inch vent in the back for easy movement and a removable sash. Based on these measurements, I estimate this to be approximately a modern size small but please double check measurements to ensure the proper fit for you.
