I'm not sure of the exact size since it's not specified, but I used to dress my child in this when they were around size 70. Worn for one season. Washed at home each time. While I don't see any noticeable stains, please refrain from purchasing if you are overly concerned about such things. Please refer to the photos to assess the condition. I will fold it up small for shipping, so please be aware that there may be some creases.
