My daughter, who is 110cm tall and weighs 18kg, wore this; she's quite slender. The size is 100, so I think it's suitable for children around 100cm tall if they have a standard build. When she was 100cm, the shoulder straps would slip down, so I sewed them with thread as shown in the photo. Please cut the thread with scissors if you don't need it. She still wore it without undoing it even now at 110cm, so I left it as is. There are stains, as shown in the third photo.
