Soft, flared skirt made of a supple material, size M, fits waists 64-70cm. - Size: M (Waist 64-70) - Material: 55% Cotton, 45% Rayon Thank you for viewing. This is a denim skirt. The color is a slightly bluish gray, which is difficult to see in the photos. I think it's different from navy blue. I am 155cm tall, and the length is around my shins. It's soft but not too fluffy, and the length isn't too long, but it covers my knees, so I loved it.
