Petit main romper, coverall Size is 70cm, which I think is equivalent to the size, or slightly smaller. I wore it as an outerwear until around 4.5 months old. I put my baby in it and put them in the stroller and car seat. The lining of the hood and the hand and foot parts are made of fluffy fabric, and the inner padding and nylon fabric kept my baby warm during the winter. There are no stains or fabric damage. Please note that the fluffy parts show some signs of wear.
