This is a maternity dress from Sweet Mommy. It has a satin ribbon detail at the waist, allowing you to adjust the waist size by tying the ribbon. It has snap buttons on both sides for nursing, so you can wear it before and after pregnancy as a nursing dress. It's a nice, clean style, so I wore it for my baby's first shrine visit (Omiyamairi). Size: S (I am 160cm tall with a standard build, and it was knee-length on me) Material: 100% polyester, Lining: 100% cotton Please purchase only if you understand that this is a used item and has been stored at home.
