Design point: It is a combination of 2 pieces. Put on the inner fleece piece and then the outer black see-through ones. There are 4 buttons at the waist front and back part to fix the two layers. So it will make sure the naturally smooth surface. Besides, you can wash the inner only, so the lace outer will be more durable. Surely, even the outer part is broken, you can purchase it only.
