I've worn this about 5 times. There's a zipper in the back, and it also has elastic. The skirt alternates between lace and simple fabric in a pleated style (see photo 4). It has a lining. It's labeled as free size, but I think it's equivalent to S-M. Waist: 30cm Length: 82cm *Please note that these measurements are approximate due to being taken by a person.
