I have to say, I love this thing. I’ve had it for years and I don’t really know what to call it. It’s sort of a shawl, poncho, sweatshirt, hoodie thing with no buttons or zipper. It’s made of cozy sweatshirt material and is perfect for a fall day with a long sleeve shirt, or summertime over a bathing suit! -Size S but would definitely fit M or L- EUC, pet-friendly, smoke-free home.
