For some couples, dressing up as superheroes or villains straight from comic books for Halloween [1] is one of the best ways to complement each other in an adorable way. It's also totally OK if you go off script and dress up as a Poison Ivy and Batman duo — just do whatever your heart tells you. Keep looking for some fun costume inspiration, and if that doesn't suit you, maybe being an emoji [2] or geeky [3] duo will.
