Long-sleeved cardigan. There is no tag and no size indication, but it was worn when my child was wearing clothes size 70-80cm, so I think it's around that size. Please refer to photos 4, 5, and 6 for details. There is a button only on the upper chest (see photo 2). I think it can be worn casually for everyday wear, as well as formally over dresses, etc. I don't see any noticeable pilling, stains, or tears, but this is a personal assessment, and the item has been worn by a child, so please refrain from purchasing if you are concerned. Please check the condition in the photos. Thank you!
