This is a dress that can also be worn as a long, tailored jacket. I purchased it from the Korean brand LUCID, so I don't know the exact material, but it's a wrinkle-resistant synthetic fiber. It has a lining. There are pleats in the back that make your waist look cinched just by wearing it. It's a convenient piece for the fall, as you can wear it as a dress by closing the front, or as a jacket by opening it.
