Maybe? The last three or four times that I went trick or treating (I don't recall how old I was... young though...), I went dressed up as a girl. My sisters just LOVED having a life-sized doll that they were able to dress up and put make up on, especially since they themselves were not allowed to wear makeup at their age. If you two do not have another sister, then I would say that it's very, very possible that she would have liked to have the opportunity to dress you up.
