Global Work Knit Size S, so I think it's around 100cm. My child doesn't like wearing knitwear, so it hasn't been used much. However, there's some color transfer from washing, and there's also some slight staining, although it's not very noticeable at first glance (it might come out with a good wash). This is a used item, so please understand its nature. If you have any concerns, please refrain from purchasing.
