I believe it was a sleeper for up to 100cm. There was no size indicated. I purchased it on Amazon. It is currently out of stock. It's a thin cotton sleeper. I've worn it several times. The color may look slightly different in the photos. Please understand. I've worn it several times, but I couldn't find any fraying or stains. I've been storing it since my child outgrew it. I will wash it before shipping it after you purchase it. Since it's been stored by a non-professional, there may be overlooked stains or dirt. I would appreciate it if you could purchase it with the understanding. #Nishimatsuya #Birthday #ChildrensClothes #NurseryClothes #BulkSale #Amazon #Pajamas
