I think this would be the perfect size for a child who is 90cm tall. The waist is a little tight. For a child who is 80cm tall, you might have to fold up the hem. There is some wear and tear, so please check the photos. The buttons are decorative. If you would like measurements, please let me know. ・Brand: LINDO Please purchase with the understanding that this item has been stored at home and worn by a child.
