Harley Quinn Arkham Asylum

10. Harley Quinn (Arkham Asylum)

It's been over four years since The Dark Knight came out, but all that time hasn't stopped Halloween from, at this point, pretty much becoming the "Six Degrees of Heath Ledger's Joker" game. While we're thankfully out of the woods when it comes to people actually dressing like the Joker (sidenote: that is way too long a time), costumes based on the long-time associate/romantic interest of The Joker, Harley Quinn, are at an all time high. As is my enthusiasm for literally any costume that isn't The Joker.

Rick Grimes The Walking Dead

9. Rick Grimes (The Walking Dead)

It's hard to make sure your Rick Grimes costume is distinguishable from your run-of-the-mill "Southern Police Sheriff" costume, which makes replicating the grizzly facial expressions and hard-bitten demeanour of the character a must. Bonus points if you spend all night talking really intensely to people, only for them to realise later on that nothing you said had any real consequence or point this season. I mean, year.

8. Homeless Big Bird & Elmo

This year, Halloween fell perfectly in between the presidential debates that coined a thousand ridiculous memes and the election that will render those same memes absolutely meaningless and obsolete. Among the hordes of "binders of women" and "horse and bayonet" couples costumes, Homeless Big Bird & Elmo stood out, its bright yellow feathers shining a beacon of well-executed topical humor across the land.

7. Misty

Last year's runner-up returns with a respectable 7th place showing, proving once again that hours of hard work and creativity are no match for horny dudes with internet connections and misplaced senses of nostalgia. It's comforting to know that some things never change. Hey, I think I get what that whole "nostalgia" thing is now!

6. Black Widow

First, she was the hottest thing about this summer's billion-dollar blockbuster (other than the sizzling bromance between Tony Stark and Bruce Banner); now, she's moved on to real fame: the CollegeHumor costume contest. This costume nails Black Wids, from the sassy attitude to the skintight jumpsuit that, let's face it, probably doesn't strictly need to be unzipped quite that far down to fight crime. Not that we're complaining.
