The comedy classic Mean Girls described the phenomenon in which some young women view Halloween as an opportunity to wear attire that's far more revealing than anything they would wear in public any other day of the year.
"The hardcore girls just wear lingerie and some form of animal ears," a pre-downfall Lindsay Lohan tells us in the film.
As you can see, the ladies of the Kardashian clan decided to skip the mammalian accessories and opted for seraphim wings instead.
Yes, the sisters went as Victoria's Secret Angels, and their looks are both extremely legit and a little weird.
Legit, because the ladies sported actual wings produced by VS, and weird, because Kendall is an actual VS Angel, which means this is a bit like a cop showing up to a Halloween party in uniform.
Kim acknowledged both of these facts in her IG caption:
"Thank you @VictoriasSecret for sending us actual runway looks and real wings to borrow for the night!!! OMG a dream come true! Got to be a Victoria Secret Angel for the night! And Kendall got good practice lol," Kiki wrote.
Let us leave aside for the moment any discussion of who had what surgically altered and just agree that all of the Kardashians are hot.
A question that's often debated by both fans and the Kard clan themselves, of course, is who's the hottest of the lot.
This is a tricky issue that's a bit like choosing your favorite Beatle.
You might personally prefer John, but you can really say that someone who picks Paul is wrong?
This is a very similar scenario, except with singing and songwriting replaced with T&A.
Take Kylie, for example.
Yes, we've seen Kylie Jenner in lingerie before. Many times, in fact.
But this time she has wings, which means it's a costume, and not what the kids call a thirst-trap.
But there's a reason that the mother of one's Instagram posts so frequently go viral.
Kendall may be the family's resident model, but Kylie is no slouch when it comes to "serving looks," as the kids also say.
This year, she gets bonus points for trotting out multiple costumes, including this Barbie-inspired ensemble.
It's both creative and self-effacing, as Kylie has been criticized for the lifeless doll-like expression she sometimes sports in her photos.
But the award for this year's funniest Kard clan costume goes to Kendall Jenner who went as a fembot from the Austin Powers series, alongside a friend who does not appear to be her new boyfriend Anwar Hadid.
Depressing fact of the day: Kendall was 2 years old when the first film in the Austin Powers series hit theaters.
Great, now we feel weird about commenting on her hotness at all!
Thanks for ruining our fun, inexorable march of time!
Well, so much for the "who's hottest?" conversation.
Of course, we reserve the right to change our minds if we accidentally piss off Kanye.
Now that he's done with politics, dude has all the time in the world to rant about pettier matters.
