This is a long-sleeved sleeper featuring Ultraman. It was given to us as a hand-me-down, but we're selling it because our son isn't interested in Ultraman. The size is L, and when worn by a child who is 90cm tall, it covers all the way to the ankles. The sleeve length and shoulder width are quite roomy, so I think it can be worn by children from 90cm to about 130cm. There are buttons at the crotch, so you don't have to worry about it coming undone, which is reassuring.
