Let's be honest: there's no decision you will make over the course of the year that will be as difficult as choosing the right Halloween costume.

It's a conundrum as old as time itself. Okay, not really, but figuring out what to wear has plagued people for years.

So, for every Cabbage Patch Kid in the '80s, Scream killer in the '90s or Britney Spears wannabe in the 2000s, just remember a lot of deep thought was placed into deciding to put on those get-ups (and let's not even get started about pet costumes).

This video examines how Halloween costumes have changed over the last century and gone from somewhat simple to a celebration of pop culture. Plus, the 2015 one is bound to get people talking, which is good because if there's one thing we need more of it's a Kardashian in the spotlight, right?
