You'd think that after all that high-brow debauchery at Allison Sarofim's annual pre-Halloween bacchanal, the fashion-y types would be sated until the evening of October 31. But no, fashionable celebrities CANNOT be held back from busting out their Halloween costumes early — and we're not complaining about their lack of impulse control, mind you. Especially when some of the costumes are this good. (And we'll be updating with more as the looks roll in.)
Taylor Swift dressed up as a plushie unicorn for an interview sesh on Elvis Duran's radio show. But we can't see the costume over the radio, Tay. Thank goodness for Instagram.
OH MY GOD YOU GUYS. BEYONCÉ DRESSED UP AS JANET JACKSON FROM RHYTHM NATION. Respect.
Over at the UNICEF Ball in London last night, the "It-Brit" girls went all out in fancy dress (that's what they call costumes in England). Gala Gordon went as a pretty spot-on Maleficent, Suki Waterhouse was a showgirl-esque Queen of Hearts and Clara Paget dressed up as "Batman" villain Poison Ivy.
Wait, did we know that model/actress/Bradley Cooper's girlfriend Suki Waterhouse can sing? Because she had jam sesh with Bryan "Summer of 60" Adams, singing Sporty Spice's part in the duet "When You're Gone." Kind of amazing.
Also in London, DJ/model/guyliner icon progeny Amber Le Bon channeled her own "Fifty Shades of Grey" to hit the turntables at a fashion-y party.
Lucky Executive Digital Editor Verena von Pfetten (who also has the best name ever after Serena van der Woodsen) and Deputy Editor Leigh Belz deftly reenact this iconic scene from "Devil Wears Prada" as Miranda Priestley and Andy Sachs, respectively.
Liv Tyler got punny with "a bun in the oven."
Man about town Derek Blasberg took the lazy way out. Maybe he partied too hard as Waldo last week.
Oh, false alarm. He and Dasha Zhukova were living Roy Lichtenstein-inspired drawings in Los Angeles last night. Well played, Blasberg, well played.
Can you tell it's Cara Delevingne under the terry cloth skull cap, crazy glasses and fuzzy mustache?
We can always depend on Team Marc Jacobs for a stellar costume.
North West is an adorable skunk for Halloween. I just can't with the cuteness. I wonder if it's a custom designer skunk costume...
Nicole Richie and her kids channel three of the 101 dalmatians.
At her Halloween bash in Hollywood on Thursday, Kate Hudson gathered her friends for a sexy "Sons of Anarchy" ensemble costume.
Katy Perry took Jeremy Scott's fast food-themed Moschino collection to the next level by dressing up a flaming Cheeto, complete with a snack-bag bag.
Jessica Alba and her BFF Kelly Sawyer channel Axel Rose and Slash in their hard partying heyday, complete with a bottle of Jack. Although, slight inaccuracy alert: That bottle should so be empty.
Someone named Andre as soccer player/coach Ricky Hill (it's a British thing), Nicholas Grimshaw as Rita Ora, and Kate frickin' Moss as Cara Delevingne. She just won Halloween.
And Rita Ora as Barbie. Second Moschino reference this season?
Turns out North West's adorably stinky costume was just a pre-game because mama Kim 'grammed this pretty epic photo of a Grace Coddington, mini-Karl Lagerfeld, herself as Anna Wintour, and little Nori as Andre Leon Talley.
Not the face, Chanel Iman. NOT THE FACE.
Sigrid Agren gets kinda mouthy.
Constance Jablonski plays the dark, fallen angel to her pal's heavenly winged one.
I was waiting for the sexy vampire thing to happen. Thank you Devon Windsor and hot friend.
Kinda high maintenance there, huh, Giovanna Battaglia?
Um, Kendall Jenner and the real Cara Delevingne as Mario and Luigi. Kind of epic.
Anna Dello Russo's terrifying masked costume (middle), which actually maybe looks like some of her regular ensembles.
Don't tell Derek Blasberg, but Phillip Lim (second from left) was also a Roy Lichtenstein piece of art for Halloween. He partied with a "disco matador," Joe Jonas as Zoolander (kind of loving it), Richard Chai as a raver and "Harvey Dent."
This might actually be my favorite: Adam Levine as Tommy Lee and Behati Prinsloo as Heather Locklear. (Because, kids, the actress was married to the Motley Crue drummer in the late '80s to early '90s.)
And, of course, another mind-blowing costume from Heidi Klum.
The Brady-Bundchen family went out for a regular-person evening of trick-or-treating. You realize that Brady and Bundchen probably rang doorbells in their Boston neighborhood and NO ONE KNEW IT WAS THEM.
Alexa Chung did her version of Sarofim's #futurism, we think.
Gwen Stefani made a pretty on-point ballerina while No Doubt band members Tony Kanal and Tom Dumont channeled Kiss.
Eva Chen's very impressive Maleficent costume included the cheek prosthetics (amazing) and Erica Domesek of PS I Made This was a pina colada — complete with a matching iPhone case.
OMG, Blue Ivy as Michael Jackson. We die.
Andrew Bevan posted Teen Vogue's Archie, Betty, and Veronica looks. Kind of terrifying, but very impressive at the same time. (What happens when they open their eyes?)
