Worn about twice. It's a black sleeveless top and skirt set, so it's easy to use. The skirt length is about 20cm below the knee (for someone 157cm tall). The skirt has an elastic waistband, so it's comfortable. Also, it's a straight silhouette, so it makes your body line look sleek. The size is listed as S, but it's about a size M. Can be delicately washed at home. Wrinkle-resistant.
