Can anyone help me figure out how to make this Halloween costume?

This may sound strange, but that's the point...





I always thought it would be funny to go to a Halloween party disguised as a chair. I would get there before anyone else and find a place in the room where I look like just another piece of furniture. After everyone was there and the party had been going on for a while I would stand up and see everyone's reactions.





Do you think this would work?





Any ideas about how to do it?

Cute, but realistically could you be in that 45 degree sitting position for that long? If so go right ahead and try it, but I don't see you sitting still for that long.
