Approximately 55 centimeters from top to bottom. I've worn it several times, but I don't see any noticeable stains. However, I apologize if I've overlooked anything. As this is a product from overseas, there may be loose threads or areas of rough stitching. Please refrain from purchasing if you are concerned about this. It has been stored at home after my child outgrew it. This is a used item that my child wore, so please understand this. Thank you.
