The Rainbow Fish
You'll have no trouble recognizing this costume if you read "The Rainbow Fish" during your childhood. This young lady decided to transform into the unique fish from "The Rainbow Fish," a German children's book that became a children's T.V. series. If you're unfamiliar with the book, it tells the story of a fish with distinctive, shiny scales, much like the ones adorning this girl's costume.
Initially, the Rainbow Fish is reluctant to share its gleaming scales with its friends, believing they make it unique. However, it eventually realizes that its friends are worth far more than shiny scales, imparting a valuable lesson to children about the importance of sharing. This girl must have been a fan of the book in her childhood, as she looks remarkably like the shiny fish depicted on the book's cover.
