Made of 97% cotton and 3% polyurethane. There is no lining, but the fabric is sturdy, so you can wear it casually with a T-shirt in the summer, and warmly with an inner layer in the winter. I bought it for maternity wear, but I wore it several times after giving birth. The photos aren't very good due to the folding wrinkles, but the vertical lines are effective. For someone around 165cm tall, the length is about 10cm above the ankle. There are folding wrinkles. Please feel free to comment if you have any questions. I will fold it up small for shipping.
