Retro Girl offers this item in a single M size, so it's essentially a free size. It's a loose, oversized knit. The neckline is also quite open. I used to wear it with a turtleneck underneath. It has a fluffy and very cute design. I often wore it with denim or black skinny jeans. It's perfect for the coming season. I will ship it folded compactly in a box.
