This is a Petit Bateau long-sleeved cardigan. It's size 18m/81cm. My child wore it around the age of one and a half. It was worn for one season. It shows signs of wear, but I didn't find any major or noticeable stains. There is a mark on the tag where a name sticker was removed. It's 100% cotton and seems very comfortable. I'll sell it to someone who understands that it's a used item.
