This extremely clever and delightfully geeky young lady gets my vote for costume of the season. She went as “Low Resolution Girl”.
That title rather sounds like it should have a superpower associated with it. The power to pixelate? “Surrender citizen, or I will make your nefarious plans unclear!” Would that be dangerous?
Maybe her sidekick could be 8-bit Boy, and together they could fight their nemesis, Dr. Ten Eightypee.
