Already Halloween for someone

I saw this the other day during one of my night walks.  It’s a discarded costume of some sort, but it is too early for this to be for Halloween and I don’t know what exactly it could be for otherwise. I just hope that the people in the summer houses really did leave for the winter and aren’t still lying motionless in their homes, the victims of whoever was wearing this. When I went back the next day, it was gone and the only proof I have that it happened it this pic.
