Julianne Hough
She has since issued an apology (don't read any of the comments on any posts about this unless you want to give up most of your faith in humanity, btw) but (charitably) I think we can all agree that this is not the best idea Julianne Hough has ever had, and that none of her friends have the sense God gave a goldfish for letting her leave the house like this. I am stunned that no one looked at her and said, "are you SERIOUS??!" Almost as stunned as I am that she decided to Go There in the first place, because, seriously, I can't believe I need to clarify this but vis a vis blackface? DON'T.
Paris Hilton
This feels about right. For a woman who desires nothing more than attention, what better costume than the most attention-getting look of the year. I'm just glad Paris didn't go all "Wrecking Ball" on us.
Molly Sims
Carmen Miranda is fun: festive, saucy, not overtly sexy but still flirty. Everyone loves a fruit-covered turban, also. It's a universal truth.
Tim Allen
Our photo service swears Tim Allen is in costume as a "baseball player," and I think we can all agree that, if so, this is the worst baseball player costume ever.
Cindy Crawford and Rande Gerber
Axl Rose and Slash is a pretty awesome costume for a couple, AND has the bonus of being super comfortable. You just have to accept that people are going to leer "HEY WHERE'S BUCKET HEAD" at you all night, and/or that the drunker people get the more likely they are to come running at you screaming the lyrics to "November Rain." "NOTHING LASTS FOREVER, CINDY, AND WE BOTH KNOW HEARTS CAN CHANGE!"
Jeremy Piven
I have no idea what The Piv is supposed to be.
John Stamos
I suspect he is technically a handsome devil.
Leonardo DiCaprio
This is allegedly Leonardo DiCaprio, which I say: (a) how can you tell? and (b) the expression on the face of the dude next to him is priceless and glorious.
Goldie Hawn and Kurt Russell
Please let them be Heidi and Heidi's Grandfather.
Kristin Chenoweth and Jake Pavelka
These two are dating, and I think we can all agree that Cheno has wide-ranging taste in dudes given that she also dated Aaron Sorkin. I do applaud the former Bachelor for going full-on Stormtrooper, but I'm not sure what Chenoweth is supposed to be? A cute SWAT?
Chord Overstreet
Chord Overstreet is apparently Jax Teller from Sons Of Anarchy, which I don't watch. I suspect this is one of those costumes that is alluring because you can create it from items in your closet, which is my usual MO and why I have popped up at Halloween as: Liz Lemon, Blair Waldorf, Anna Wintour (that one needed a wig), and Janice Dickenson.
Isla Fisher and Sacha Baron Cohen
I have no idea what these two are supposed to be either, but they are legitimately chilling.
Adam Lambert
THAT, my friends, is how you wear a turban.
Adam Lambert
A twofer from Lambert. I hope he runs into Rande Gerber and Cindy Crawford because maybe he can join the band.
Jesse Tyler Ferguson and Justin Mikita
These are rather charmingly half-assed.
Nicky Hilton
Sexy Schoolgirl, the go-to for women everywhere short on time and long on desire to look cute (I've done it myself). But the real hero of this photo is the girl who wisely turned her face away from the camera, and who decided to go to a party at the Playboy mansion as a Bunny wearing high top Converse.
David Arquette
This is honestly not that much different from what he usually wears.
Vanessa Hudgens and friend
The best part about this is that SHE HAS WORN THESE BOOTS BEFORE.
Alessandra Ambrosio
I played The Queen of Hearts in a stage performance of Alice in Wonderland many many years ago and I do NOT recall the costume involving this much leg.
Jessica Lowndes
Poison Ivy? The 90s ARE back!
Chelsea Handler
This is not a costume, Chelsea.
Kelly Brook
Um, sexy...Marie Antoinette, post-guillotine? I don't even know. I'd love to see someone just show up dressed as a slice of pizza. Full-sized slice, not a Sexy Slice.
Michelle Trachtenberg
This is fun, though. I miss Snarky Michelle Trachtenberg on my TV.
Maksim Chmerkovskiy and Friend
Well, I only hope one of them went home with Kelly Brook. Not QUITE the right era, but close enough.
Fergie and Josh Duhamel
Fergie and Josh Duhamel look pretty impressive, although I'm not sure how Riff Raff and Elvira know each other. In fairness, if they met on OK Cupid, they probably WOULD hit it off.
Lauren Conrad and William Tell
The internet tells me LC is "a fairy queen."
Gabriel Mann
My eyes tell me Nolan is a skeleton.
Grace Phipps
Grace Phipps was fairly annoying on Vampire Diaries and I am very pleased the show is pretending April never existed. HOWEVER! Her Annie Hall is ADORABLE.
Lance Bass, Michael Turchin
This is Lance's fiance, and I FULLY endorse these costumes. One might even call them excellent.
Jennifer Morrison
As for Jennifer Morrison, she's Cher Horowitz from Clueless, which officially makes this one of my favorite things she's ever worn.
