I'm selling this because my child has outgrown it. It's 100% cotton, very comfortable to wear, and I loved it. It has been used, but there are no noticeable stains. How about it for spring? It's a size S, but I usually wear a size M, so I think it's a relaxed fit. It's difficult to measure the shoulder width, but it's about 40cm from seam to seam. The length is about 62cm, and it covers a little bit of the hips. Please understand that this is a used item. Returns and claims are not accepted. It will be folded and shipped, so please excuse any folding wrinkles. Thank you. Thank you for looking.
