I purchased this from MUJI, but I only dressed my child in it once and then missed the opportunity to use it again, so I've been storing it. I'm selling it now because it was too small when I tried to dress my child in it this year. It can be worn as a single shirt or as a light jacket in warmer weather. It has a cute blue and white striped pattern ☺︎ Please understand that this is a used item.
