These are slit pants from AP STUDIO. The color is black, and the size is 36. Made of triacetate and polyester, they are hand-washable at home. They have an elastic waist and the fabric feels smooth and comfortable. Although they might look see-through, they are not when worn. The silhouette is very beautiful and makes you look slim! I usually wear size 38, but I chose size 36 for these, so I think they can be worn by people of either size. Measurements (laid flat): Waist: 32cm (elastic) Hips: 49.5cm Thigh width: 27cm Leg opening: 16cm Rise: 30cm Inseam: 67cm Please allow for some margin of error.
