According to Google, Harley Quinn is America's most searched-for Halloween outfit - but which version of the DC villainess will you be dressing up as?

Whether you’re planning to go as a traditional ghost, zombie or vampire, as a slightly less traditional but impressively topical lion-killing dentist, or as a sexy Donald Trump, the internet isn't exactly short of creative Halloween outfit ideas.

But, this year, it looks as if a host of film fans will be drawing inspiration from Warner Bros’s forthcoming DC adaptation Suicide Squad, and dressing up as notorious psychiatrist turned deranged criminal Harley Quinn. 

True, the film isn’t out until 2017 – but new cast photos and a deliciously dark trailer, featuring The Wolf of Wall Street star Margot Robbie as Quinn, have already captured our imaginations (or at least the costume-making side of our imaginations). According to Google, Harley Quinn is the most popular costume search this year in the US.

Quinn (her real name is the much less catchy Dr Harleen Frances Quinzel) is a relatively recent, but notably popular addition to the DC world.

She was first introduced in 1992, via the Warner Bros television cartoon Batman: The Animated Series. Originally a psychiatrist at Gotham’s notorious Arkham asylum, Quinn ends up falling madly in love with The Joker and turning to a life of crime.

In the original animated series, she sports a distinctive black and red Harlequin outfit, complete with matching jester's cap. But across the years, the character – who quickly made the transition to DC comic book regular – has been represented in a number of different ways, and in a number of different outfits.

In other words, if you’re planning to dress up as Harley Quinn this year, there’s no reason why the Suicide Squad incarnation should be your only port of call.

Here’s our round up of some of the various Quinn costumes we’ve seen.

With dual-dyed blonde, red and blue pigtails, a choker, and a ripped “daddy’s lil' monster” t-shirt, Robbie’s Quinn has a fun, punkish edge, and was a popular choice at various comic book conventions earlier this year.

The look was in fact directly inspired by an iconic Debbie Harry photoshoot: in the late Sixties, Blondie guitarist Chris Stein took pictures of the band's singer dressed in a torn Vultures t-shirt, sporting a studded belt very similar to that worn by Robbie.

Other Quinn costumes – including the kid-friendly ready made outfit below – appear more inspired by the animated Nineties TV series, and by some of the earlier comic books featuring the character.

The look also works quite well if you happen to be a cat.

Revamped Quinn

In 2011, DC Comics decided to launch a “sexier” version of the character: the all in one outfit was swapped for a more revealing bustier and low cut trousers, and a striking half-red, half-black pigtailed hairstyle was revealed. (In her earlier incarnation, Quinn’s hair was blonde, and usually hidden by her cap.)

Unsurprisingly, this version of Quinn (complete with bleached white skin – her charming on-off boyfriend dipped her into a vat of acid) has proven to be one of the more popular costume choices.

Arkham Asylum Quinn

In the 2009 computer game Batman: Arkham Asylum, Quinn's "medical credentials" are played up, and the character is portrayed as a sort of "naughty" (read: evil and insane) nurse. When it comes to cosplay, fans often choose to add in additional blood splatter, making this version of Quinn a particularly apt choice for Halloween.

In the game's  2011 sequel, Arkham City, Quinn's outfit and appearance are more similar to the "revamped" version described above.
