This is a mermaid skirt. It's equivalent to a kid's size 160, but it's simple, so adults can wear it too. I've kept it in a garment case after washing it, but I'm selling it because I haven't had a chance to wear it. Because it's a mermaid skirt, it might be a little difficult to open your legs. Length: Approximately 70cm, Waist: Approximately 66cm (adjustable) Please see the image of the tag for the material. *I've set the shipping time to 4-7 days just in case, but I will ship it as soon as possible.
