This item can be worn as a light jacket, or it can be styled with a belt to cinch the waist. The material is unknown as I have cut off the tag, but it has a slightly satiny, smooth feel. It doesn't shine as much as satin. Also, it is not see-through. I think it's easy to mix and match because it's brown. Shoulder width: Approximately 43 cm Length: Approximately 72 cm Sleeve length: Approximately 57 cm Width: Approximately 50 cm (Measurements are approximate. Please understand.) I think it's a small S size, more like an M. Please be sure to check the photos for the areas with stains. I don't think there are any other stains, but please refrain from purchasing if you are concerned, as it is a casual inspection.
