What should I be for Halloween?

I know it is kinda early but I wanna know my options so what should I be for halloween? Not something unoriginal like a witch or a monster or something from Friday the 13. Something creative that no one would think. An example of creative my Mom's friend dressed up as Flo from the progressive commercial. That is what I mean by creative. And it has to be age appropriate for an 11 year old. And for those of you who are saying you are too young to have a yahoo I am on my cousins account that she left signed in. ten points best answer!!
