Purchased two years ago from an online site. Only tried on, never worn. It's an American size, so the tag says XS, but it feels large on me, and I usually wear a size M, so it's more like a size L. It's unused and has been stored in a drawer, so the condition is good. The waist is 30cm when laid flat, but it has some stretch. The length is 33cm. There are pockets on the right back and on both sides of the underskirt. Thank you.
