Very unique one piece jumpsuit no brand

Very unique one piece jumpsuit no brand. There is no size on the piece but it measures approximately 60 inches from shoulder to bottom. Would be great for a costume or just to wear out. Layer with a blue Jean jacket and that would be so cute with some wedges. Sleeves are flared and open. Lots of stretch to it, zips up the back and elastic in the neckline. Selling for a friend so I don’t know much about it. Thanks for looking 👀
