Worn only once at the nursery school's Halloween last year. My child liked it, but said they won't wear it anymore. There's no size label, but I think it's around 120cm. In the photos, my child was 110cm tall and weighed 16kg, a slightly slender build. I hope you can use the photos as a reference. It's a slip-on type, so it doesn't get in the way when using the restroom.
