Formal Romper 90 Usage is unknown, but I think it's relatively clean. It was worn for the child's first birthday celebration (issho-mochi) and the "erabitori" ceremony, as well as for birthdays, Halloween, and sibling events. The trousers have a houndstooth pattern. Front opening with snap buttons. The vest part is sewn to the shoulders and cannot be removed; it has regular buttons. A decorative pocket is attached to the chest. A ribbon is hand-sewn to the neckline. It is attached with snap buttons on both sides, so please discard it if you don't need it. Thank you.
