Colorblock Paper Airplane Sweatshirt

Super cute patchwork patterned sleeves with a perfect little flying paper airplane detail. Size and brand is unknown. Approximately 23” armpit to armpit and 26” total length with 21.5” sleeves. I’m guessing it’s 100% polyester. It has some stretch but not the cotton kind of stretch. Preowned condition with some pilling, especially on the inside. See photos.
