This is a Hanfu dress purchased in Hong Kong. There's no clear size listed, but it fit my daughter perfectly when she was in her last year of kindergarten, so I think it's around 120cm. For reference, I've included a photo of her when she was in her last year of kindergarten. It was only worn at home for photos. The fabric is thin, and it's put on and taken off with a zipper in the back. How about it for Halloween, Chinese New Year, or Mid-Autumn Festival? I don't think you can easily find this in Japan. The gentle pink color is lovely.
