My child outgrew this in a year. It's labeled XXXL, but I bought it after searching for sizes 140-150. (It fit perfectly when they were 140cm, but now at 150cm, the inner shorts are visible) They didn't wear it that much, but the seat of the pants turned sandy-colored from a trip to the river. (It's a one-piece design with inner shorts, so they're not visible when standing) I have a picture of the back, and because it's a separate top and bottom, the stomach is visible when it rides up, which feels a little insecure. It wasn't a problem for us since we mainly use a backyard pool, but it might be something to watch out for with water slides.
