Thank you for viewing. This item is unused, having only been pre-washed, and I purchased it from someone else. The size is EUR 56cm. I bought two sets, and since my child outgrew one set after using it, I am offering this unused one. The fabric feels great, and the pants have a waistband like a belly band, which I loved so much that I dressed my child in them almost every day. Because my child was small at birth, they were able to wear them even around 6 months old. The design is cute, and the fact that it's organic cotton is also recommended.
