Approximately 68 to 70 cm. I measured it with a 17 cm ruler as I don't have a measuring tape. I wasn't sure of the child's size, so I chose 120, but please compare it with a dress you already have. It shows signs of wear. It's velvet-like, so it easily attracts dust, and appears white depending on the light. The tag is also beige and looks old, but it can still be worn. Please use it as everyday wear. Please purchase only if you understand that this is a used item.
