Every year, without fail, pop culture acts as a huge influence on Halloween, and 2015 is no different. The year's top movies, television shows, celebrities, politicians and scandals all serve as fodder for juicy costumes. When it comes to Halloween, it seems nothing is off limits.

"Inside Out," the smash hit Disney/Pixar children's film about the emotions at play within us, for example, is burning up the internet as an innovative group costume idea for adults. Trendy website Brit + Co even has a DIY tutorial for how to make the costumes at home.
