Margot Robbie made a few waves when her take on Harley Quinn premiered in the latest Suicide Squad trailer earlier this year, but I doubt anyone could have foreseen just how popular her costume would be come Halloween time. According to Google's 'Frightgeist' rankings, Harley beat modern classics and tried-and-tested favourites alike, keeping Star Wars, Minions and even Batman as being the most searched Halloween costume of 2015.

And wow, we can certainly see why! Here are a few of the best Harley's we found on social this morning.
