The fabric is a thin polyester material. It doesn't have the stiffness often found in casual wear, and has an elegant drape. It's also wrinkle-resistant, so you can wear it without ironing, which is a nice feature. It's a material you can wear year-round. The silhouette is a relaxed fit with a moderate amount of room, but it's not overly oversized. Also, round elastic is threaded through the sides of the waist. This allows you to adjust the length, of course, but also to gather the fabric and create a slightly sweeter look, expanding the range of arrangements. The back neckline's corner button can be undone for easy on and off. You can wear it year-round, and the large slit in the back allows you to enjoy layering with innerwear. I've worn it twice, but I think it's in good condition.
