This is a Ralph Lauren dress. It's US size 3T, which is about 90-100cm in Japan. It seemed a bit tight around the neck for my chubby eldest daughter. It fit my slender younger daughter with room to spare. It was for events, so it's only been worn a few times, but it has some wrinkles from being stored at home. They should come out with washing. It's perfect for going out in this season.
