Purchased for a party, and the tag has been removed, but it's new and unused. There's no size label, but based on the fit, it's around XL. It's slightly larger than L size. The color is black, but the upper part has a three-dimensional pattern, and the lower part is asymmetrical with movement and a see-through material, giving it a luxurious feel. I'm selling it because I don't have a chance to wear it. Although I'm a novice at measuring, the approximate width is 44 cm, and the shortest length is 90 cm. When I tried it on, the seam was right around my stomach, so I thought it would hide a big meal, which is why I bought it.
