This is a unicorn costume from Great Pretenders, purchased in the US. It's from a shop that sells many cute unicorn costumes. The size is 4-7, for ages 4-7. It's a skirt that matches the headband. The skirt has glitter and is fluffy. Depending on which way the rose petals are facing, the green adhesive backing is visible. See photos. It's perfect for Halloween, and I also wore it to USJ's Easter event, where it looked cute and spring-like. I will put it in an envelope and ship it via Mercari.
