This item looks like knitwear, but it has a 100% cotton lining, making it comfortable for young children to wear. The neckline can be closed with buttons, keeping you warm. It appears yellowish-green in the photos, but the actual color is a bit more yellow. The color in the third photo is the closest. It has been washed many times and has a lot of pilling. However, thanks to the fabric texture and color scheme, it was almost unnoticeable and stress-free. This is a used item, so please purchase it if you don't mind the signs of wear and tear.
