This is a white faux leather mermaid long skirt. It's a free size with elastic in the back, but for me, who has a larger lower body and wears an L size, it was too tight. I loved the cute design, but I've decided to part with it. All the buttons in the front can be unfastened, but some are sewn in place, so even if all the buttons come undone, the skirt shouldn't fall down. It has only been worn once. Thank you.
