These pajamas feature fun patterns of astronauts, rockets, and UFOs, and come with a belly band. The color is navy with white and yellow patterns. The fabric is not thin, but more like a sweatshirt. It has color buttons and buttonholes, perfect for practicing buttoning. I think these pajamas can be worn for a long time. *This is a used item.
