We decided to be Lila and Fry at our first Halloween together. We colored my hair violet and his hair orange. I made a big eye and found a blaster. Then we just wore the same clothes as characters do in cartoon and-voila! Here we are simple and fast.
P.S. I made my eye from constructional net at the outside and from foam rubber at the inside. Then I colored it with white spray painted and added a black apple of the eye and few huge eyelashes.
