I bought this on Mercari because I wanted to wear it, but I didn't end up putting it on my child, so I'm quoting the details from the original seller! [Size] (Measurements by a non-professional) Length: Approximately 34.5cm Shoulder width: Approximately 25cm Width: Approximately 31cm Sleeve length: Approximately 26cm - 100% cotton - No stretch The name on the tag has been blacked out with a marker. There is some staining on the tag, but there is no noticeable damage to the fabric, so I hope someone can make use of it.
