Purchased from mikihimeji. The material is probably cotton. It can be worn as a coat in early spring, and can be worn year-round depending on the inner layers. The attached string can be tied in the back as shown in the image, even without fastening it, which changes the atmosphere and is stylish. After purchasing this old, used item, I kept it in storage because I couldn't bear to wear it. As shown in the image, there is a flaw in the fabric on the back. Please understand that this is an old item. I will fold it compactly when shipping. Using the nest Robe tag. nest Robe Grenier
