The size is 130 cm. It's made of a sturdy waffle knit material. I received it as a hand-me-down, so it might have originally been pajamas. My daughter wore it as pajamas with other pants. There's a faint oil stain on the right side. It's not very noticeable, but please refrain from purchasing if you are concerned. Otherwise, there are no other noticeable scratches or stains. Please understand that this is a used item and has been stored at home.
