I'm selling this item because my child quickly outgrew it, so it was only worn a few times. The inner tag has been cut off because it was irritating. It's a foreign brand, and the size is for 6-year-olds. I think it's roughly 120cm, but it's a slim fit, so I think it would fit children from the end of kindergarten to small first graders. My child wore it when they were 5-6 years old and wearing 110cm. It's from Cotton On, an Australian brand.
