This is a nursing dress I used a few years ago. The front part can be lifted up and has a hook, allowing for breastfeeding. It has a chiffon design, and the sleeves are sheer. It was useful because it could be worn in a dressy style. It was also useful for the Hatsumairi (first shrine visit after a baby is born). I don't see any stains, but please refrain from purchasing if you are sensitive to items stored at home.
