Purchased at Isetan Shinjuku and only worn for a few hours on the first birthday, so it's in beautiful condition. The included overpants have been worn several times. The pleats are beautiful, and it's a lovely item that makes the child look intelligent even at a young age. I think it can be worn for attending classes, lessons, and formal occasions. #RalphLauren #Polo #KindergartenEntranceExam #NavyOnePiece #Classroom #BabyFormal
