This is a women's set-up. The color is navy, and the size is a size 9, which I believe is equivalent to a size M. Purchased in 2015. It was very useful for weddings, Shichi-Go-San (a Japanese festival for children aged three, five, and seven), entrance ceremonies, etc., and I could wear it even when pregnant. The lace that peeks out from the back and the stomach area is cute. The inner layer is a bare-top style pants. Originally, it had shoulder straps, but they have been lost. Dry cleaned.
