This is a set of a two-way romper that looks like a montsuki hakama and Japanese-style socks that look like you're wearing zori sandals. I purchased this from another seller and wore it once for the Okuizome (first meal) ceremony. The previous seller purchased it last year and wore it twice. How about it for New Year's or other occasions? It can be worn by newborns. Two-way all Material: 100% cotton Sleeve length: Long sleeve Size: 50-70 Brand: Nishimatsuya Socks Size: 9-12 Brand: Belle Maison No price reduction.
