This is denim, but the lining is a soft fabric like a T-shirt, so I think the child wearing it would have found it comfortable against their skin ☺︎ Also, the hem can be folded up once and secured with a button, so it can be worn for a relatively long time. There might be a few pills on the lining, indicating some wear. It's stylish on its own, and I loved it so much that I wanted to take good care of it, so I only wore it a few times for outings. However, it is a used item worn by a small child, so please refrain from purchasing if you are concerned about minor details. It's labeled as 6-12 months, 70cm, but it might be a little big. Perhaps because my child was a bit small, they were able to wear it until around 1 year old. Instant purchase is available. I also have many other baby clothes from BabyGap and Petit main that my child has outgrown. I will also offer a discount for combined purchases, so please take a look at my shop if you'd like ＊
