The 50 Hottest Celebrity Halloween Costumes

Where, Year: Yelloween party at Tao Las Vegas, 2009

Ashley Greene's got nice plumage. In peacock terms, that means tail. In human terms, that means butt. Just so you know. Judging by her straight-faced photos, she needs to loosen up a bit at her own party. Shake her tail feather a little bit. Maybe some Grey Goose would do the trick? Or would that technically be cannibalism?

Where, Year: Heidi Klum's 11th Annual Halloween Party, 2010

Hear us out; cheetahs are extremely fast to catch their prey so obviously Ashanti's heels would not help her in the wild. But this was Heidi Klum's annual Halloween Party and her prey, instead of anetelope or whatever, was probably men. She doesn't have to hunt them down if they come running to her.

Where, Year: XS Hollywood Halloween Party, 2009

While there's no replicating Pam's effect on us in the '90s, Holly Madison could be this generation's most suitable substitute. But we have to check her qualifications first (...imagines Holly running on a beach...). Yup, she's got the part!

Where, Year: Masquerade Night at the Alex and Ani Showroom in Tribeca, New York, 2008

This is Lydia Hearst owning who she is: one of New York's most scandalous socialites. From tales of excessive partying, to high-fashion modeling, to "dating" (i.e., making out in public with) Aubrey O'Day, she's essentially paying tribute to the tabloid that made her infamous. And she's a Hearst? Oh, Lydia, how meta.

Where, Year: At home, 2008

Her costume comes equipped with Spencer Pratt as an inmate behind a portable set of bars. Metaphorically speaking, this would work better vice versa or if Heidi was dressed as a nurse in a psych ward and Pratt donned a straightjacket. Actually, given that she's finally split from the monster with the flesh-colored beard (well, maybe, but who really cares?), we'd much rather see the latter.

Where, Year: Tao Halloween Party sponsored by 944 and Hornitos, 2008

Is she the Queen of the Undead or just a hot girl with a skull fetish? Who knows? It's Halloween, and you can get away with wearing anything. Plus, the shorter, the tighter, or, essentially, the sluttier it is, the more people are willing to overlook the fact that you're not actually wearing a costume. And come on, it's Tera Patrick—at least she's wearing something.

Where, Year: Steelo & Snow Queen Vodka Halloween Costume Party, 2007

Pshh. We wonder which dude she borrowed this jersey from. Alright, we came off sounding like a jealous ex-boyfriend there, but we can't control our contempt. She's got a body you'd want to tackle, or at least two-hand touch, and it's just not fair that we can't play with her. That's all. Besides, her boyfriend would have to be Verne Troyer or a 5-year-old child to fit in that jersey.

Where, Year: Rok's Inaugural Halloween Bash, 2009

Let's count the reasons why theaters were better back in the day: cheap tickets, classic movies, and, most of all, theater candy girls. Now we get tickets that cost half our salary, Vampires Suck, and sweaty, overweight dudes greasing our popcorn. Yes, Carmen makes us nostalgic for a simpler time.

Where, Year: Heidi Klum's Seventh Annual Halloween Party, 2006

Can ve haz a sep of milk frum yer teet pleez? What? It's a legitimate question to ask a milkmaid, all the more so a German milkmaid. The winner of Germany's Next Top Model made an appearance at her comrade's Halloween bash dressed like she came straight out of a traditional German village, whistling and skipping onto the red carpet.

Where, Year: Dream Halloween

Halloween wouldn't be complete without its queen: Elvira, Mistress of the Dark. She embodies the Halloween spirit even on a 100-degree July day. Ironically, over the past three decades that she's embodied the character, it looks like Cassandra hasn't aged a day. Hmmm, maybe she's undead....

Where, Year: Heidi Klum's Eighth Annual Halloween Party, 2007

From hippies to hipsters to hipsters as hippies, Devon Aoki is bridging the generational gap in this totally psychedelic, far-out, groovy costume. We're half expecting her to do the twist and half expecting her to bust out a joint. But if she really wanted to get into character, she could always give out free love. We're too young to really understand what that is, but our dad used to tell us how awesome it was.

Where, Year: Heidi Klum's Ninth Annual Halloween Party, 2008

Out of all ten million of Heidi Klum's costumes, we chose this one. Why? Because have you ever seen anyone else ever in life wear this? No. Her originality makes up for the scary blue face. Not to mention, her dedication to the holiday is unmatched. Her annual Halloween party has become the go-to spot for the hottest celebrities of the moment. Come to think of it, this costume is perfect; she's got enough handshakes to go around for all of her guests.

Where, Year: The Tyra Banks Show, 2009

We can't decide if this is genius or just sad. What better person for a fading superstar to dress up as than the hottest thing in pop culture at the moment? In all honesty, Tyra as Kim is a good look for Tyra, though. If she decides to continue her "celebrity" theme this year, we're proposing she be herself during her Fresh Prince of Bel-Air days.

Where, Year: Heroes vs. Villains Halloween Party, 2009

At the Heroes vs. Villains party, Kat Deluna went with the latter by dressing up as the Greek goddess Medusa. As the myth goes, any onlookers who gazed upon Medusa would turn into stone. Fittingly, Kat inspires a similar effect; yet the stone-forming occurs in one centralized part of the male anatomy.

Where, Year: Third Annual Play-N-Skillz Halloween Bash at the House of Blues, 2009

Eat your heart out, Mickey Mouse! It'll be kind of hard to drop the daddy's-girl rep in a costume that screams, "I'm still a child!" Then again, she's got on the do-me version that you'd wear to provoke your parents. Now all she's missing is a dude they would disapprove of. That's our cue! "Hi, our name is Dude Your Parents Would Disapprove Of."

Where, Year: Golden Blast Halloween Party, 2008

If we came home to Michelle Trachtenberg sleeping in our bed, we wouldn't spaz like the Seven Dwarfs did. We'd probably just crawl right in there with her. If the pale beauty happened to wake up alarmed that we're creeping next to her, we'd calmly explain the situation. After all, she did break into our home, and we have rights!

Where, Year: The SKYY Orange Halloween Party, 2004

This was Mischa Barton during her prime. Notice how nice and showered she looks. She looked cute and perky as a cancan dancer back in the day, but if you put her back in this same costume today, you'd mistake her for a zombie. Needless to say, Mischa, bring back the Marissa Cooper version of you: still troubled, yet tan, toned, and with a sense of smell.

Where, Year: Halloween Eve Costume Party at Marquee, 2008

Mariah Carey is covered in cookies, and only cookies. If you say it out loud, it sounds even more glorious. But if you say, "Nick Cannon is the milk that covers her cookies," you just want to throw up. So, we'll just take our cookies dry, thanks.

Where, Year: Private party, 2008

For some reason, the line "I'm sorry officer, we didn't mean to be bad" sounds a bit awkward in a man's voice. It just doesn't really work. Maybe we'll just skip the dirty talk and head straight into the part where Traci handcuffs us. We'd rather she do it while wearing her red one-piece from Baywatch, but this purported "police" getup have to do.

Where, Year: Out and about on Halloween, 2010

Michalka won "Most Depressing Halloween Costume" in 2010 for her French Maid Vampire. Yeah, she was a woman who became an immortal maid. Not only does she have to suck blood to maintain a lifeforce but she has vaccum and suck up dust to maintain a livelihood.

Where, Year: At home, 2009

There couldn't be any more of a perfect costume for Kim than Jasmine—besides the Naked Cowgirl, of course. But who didn't see this coming…and/or fantasize about it happening? Kim is Jasmine personified and probably the type of chick the pervy Disney animators envisioned in creating the character anyway.

Where, Year: Imperia Vodka Halloween Party at New York City's Rose Bar, 2007

Oh, we remember this night! We attended this party too, and we dressed as King Midas. We've gotta apologize to Gemma, though; we should've warned her beforehand that everything we touched turned into gold. Oh well, it's a good look for a goddess.

Where, Year: Hard Rock Hotel and Casino Resort, 2005

This is Christina making her personal life public, i.e., possibly moving the role-playing out of the bedroom. We're not saying she does role-play, we're just saying there's a strong chance this getup was already in her closet.

Where, Year: Halloween Party hosted by Audrina at Les Deux, 2007

We know she's the poster girl for reality TV, but it would be nice to see her really get into the character of this outfit and embrace that curse-like-a-sailor mentality. We know she can already spit some gossip, get in a good argument with her man, and reduce Spencer Pratt to a peanut, so that mouth of sea men might not be so hard for her to adopt.

Where, Year: Heidi Klum's 10th Annual Halloween Party, 2009

The chick from The Vampire Diaries dressed up as a vampire. Go figure. But then again, she actually looks like your typical fanged female here, and a hot one to boot. Besides, who's seen a classic vampire post-Twilight? (crickets...) Apparently, they are all pale, brooding, and oversexed now. Not Katerina. She's even got the blood dripping down the corner of her mouth from her pre-party feast. By the way, sorry about that, Kat, we get a little messy sometimes.

Where, Year: TABU Ultra Lounge Halloween Party

Holy Annalynne, Batman! The 90210 actress may not have intended to step out on the town to fight criminals, but she surely had to fight off the dogs...from drooling all over her outfit. It's still missing something though. You know what would be the perfect compliment to this outfit? A crotch-rocket.

Where, Year: Pur Jeans Halloween Bash, 2008

What we love about girl groups is that they come as one unit. So when they're all dressed up in costume like this, we get mermaids and philosophers and little lost girls and fairies, all at the same time! When, aside from sororities, does that ever happen?

Where, Year: Heidi Klum's 10th Annual Halloween Party, 2009

Vampires with guns don't make sense. They're already dead anyway and they're a bitch to kill. Ironically, Buffy the Vampire Slayer's former vampire killer is now a vampire and a killer...of mortals. Well, all we can say is: Who knew Benedict Arnold could be so hot?

Where, Year: Hpnotiq's Halloween Party hosted by Audrina Patridge in Hollywood, Calif., 2007

Marie Antoinette did not have the best reputation when she was alive. But she's become a cliché in popular culture: a woman known for promiscuity and an excessive lifestyle. Well, if Marie looked anything like Christina does (even the undead version), we can't blame her for the insane amount of propositions she must have gotten.

Where, Year: Heidi Klum's Annual Halloween Party, 2004

From awkward princess to topless rich girl to Egyptian goddess, Anne Hathaway has successfully broken out of the Disney mold and created an Oscar-worthy career for herself. Her costume is impeccably representative of exactly the praise she deserves. Bow down, citizens!

Where, Year: Jimmy Kimmel Live, 2009

If Paris is playing Dorothy, then which of her supporting male counterparts can we play? The Lion, the Tin Man, or the Scarecrow? You already know the Lion's king and the Tin Man is stiff. Plus, we can rule out the Scarecrow because he's...a scarecrow. Nevermind. We'll just have Paris choose which version of ourselves she'd like to accompany her to her probably raunchy, snowy, chaotic fantasy version of Oz.

Where, Year: BloodLust Ball at the Hampton Court House, 2009

Apparently the U.K.'s most infamous TV personality and actress, known for her plastic surgery and snogging with her D-list boyfriend, is trying to break into the U.S. mainstream. Good job trying to make yourself stand out, Katie—in a leather corset, a thong, and a tail! Or wait, is it Jordan?

Where, Year: Heidi Klum's Third Annual Halloween Party at Capitale, 2002

Despite all the prancing around in lingerie that a Victoria's Secret model does, they can wear clothes, too! Just check out Chuck's latest villainous operative, model Karolina Kurkova, in this classic flapper outfit in the early 2000s. Actually, given the high-fashion modeling she does, she might've just come directly from a photo shoot in this outfit.

Where, Year: Cavalli Cipriani Halloween Ball, 2007

Tally-ho! Tally-ho! All hands on deck! We've got to save one of our own from the enemy fleet, the Dallas Mavericks, approaching! Porschla Coleman is now in the grips of husband Jason Kidd and we cannot stand idly by. Wait, we're just getting word in that she has given birth to his fifth child. Alright, stand down, men. She's a lost cause. We'll always have this photographic memory of her anyway. Now, who wants a tuna sandwich?

Where, Year: Hallow's Eve at a haunted house bungalow, 2005

Word association: You say, “Lindsay Lohan,” we say, “Fire...woman!” Naturally. Needless to say, could there be any more appropriate a costume for Lindsay at THAT time? No orange jumpsuit jokes. We did emphasize at that time.

Where, Year: 2033: SVEDKA Vodka Adult Playground Series at 1 Oak, 2009

They sell this getup at Party City under the name "Mile-High Pilot," so there's clearly a warning on the label stating what kind of attention a chick would get in this outfit. We trust that Blake has a sound-enough head on her shoulders to consciously choose this costume for a reason. Awkward sex in a tiny bathroom, perhaps?

Where, Year: Melyssa Ford's Birthday Celebration, 2007

"Hot" describes Melyssa Ford. Melyssa Ford's last name is like the car company. Ford, the car company, makes Mustangs. Mustangs are fast cars. Fast cars can be race cars. Race cars need a race car driver. A race car driver is exactly what Melyssa is dressed as. Therefore, Melyssa Ford is a hot race car driver. Do you see what we did there? Yeah, you really didn't need that analysis to notice the blatantly obvious.

Where, Year: Heidi Klum's 10th Annual Halloween Party, 2009

If the devil looked like her and was sitting on our left shoulder telling us naughty things to do, our lives would be pretty fucked up right now. Recently, she's been spotted out with Yeezy, so we're not going to blame him for any poor decisions he makes during their alleged time together. Who would have the strength to say no?

Where, Year: Halloween event at the Painted Turtle, 2010

Okay, we admit we had to take a swing at this one. Is Scherzinger a sexy Mad Hatter or is she just a fan of tiny hats? Regardless, she had us losing our minds in this skimpy costume.

Where, Year: Private party, 2009

Interesting choice, Beyonce. Although not the most original, or most flattering, choice of costume, our Spidey senses are still tingling. That's the point of Halloween nowadays anyway, isn't it? Well, thanks for saving us from our arch-nemesis, Blue Balls, Ms. Knowles. Gotta love our friendly neighborhood Spider-Woman.

Where, Year: Cavalli Cipriani Halloween Ball, 2007

Ms. Officer over here showed up as Diddy's bodyguard, although her outfit kinda defeated its stated purpose: Guards are supposed to be imposing and keep people away, not attract more attention. So, yeah, it completely makes sense to have the most attractive chick in the room post up by your side all night. That definitely eliminates the chance of other dudes doggin' you.

Where, Year: Heidi Klum's Seventh Annual Halloween Party, 2006

Now, this is a delightful sight to see. We can already imagine Alyssa the fairy, fluttering around our nighttime fantasies, getting fairy dust all over our sheets. As long as the glitter doesn't get in our eyes, we're cool.

Where, Year: Cavalli Cipriani Halloween Ball, 2007

Calling someone a modern-day Cleopatra is a serious claim to make. To say that, the woman you're referring to must be exquisitely gorgeous, graceful, charming, and intelligent. So, the question now is: Is Petra Nemcova deserving of such a title? The answer is yes. Being a supermodel who makes men all over the world bow down is a given. But her intelligence, grace, and charm are evident in the charitable organizations she supports, including the one she's created, the Happy Hearts Fund.

Where, Year: Robert Cavalli Halloween party, 2007

Every man's dream is for a Victoria's Secret model to double as a Playboy playmate. You'd have the assurance of her legitimacy, and you’d find out exactly what Vic's been hiding behind her lingerie all this time. Thank you, Alessandra, for showing us the possibility of this becoming a reality.

Where, Year: I Dream of Audrina party

Three wishes: 1) Audrina dressed up like this. 2) X-ray vision. 3) Getting back all the time we wasted watching The Hills.

Where, Year: Heidi Klum's 10th Annual Halloween Party, 2009

Without the stripes, this would look straight out of Frederick's of Hollywood. But there are stripes, which make the 90210 actress a legitimate official in our handbook. Can you imagine her officiating a game though? It would either be the lowest or highest scoring game in the history of sports: lowest because she'd be such a distraction; highest because every dude on the team would all of a sudden play like an MVP to impress her. Now, how do we get that backfield in motion?

Where, Year: Private party, 2005

No one goes to Hooters for the chicken wings, and no one wears a Hooters uniform because they really like the restaurant. Chicks do it because that white tank top and those orange spanks are instinctively associated with hot girls. Plus, it doesn't require any effort, unlike trying to sexify a nun’s outfit. Well played, Meagan, well played.

Where, Year: Modeling Victoria's Secret Halloween Costumes, 2010

If sailor women looked and dressed like this in the Navy, there would never be a need for recruits. In fact, we probably wouldn't even be here bringing this to you. We'd be sailing the seven seas and swabbing our deck. What can we do to make this happen without compromising the integrity of the U.S. armed forces? Seriously, we're accepting ideas.

Where, Year: M2 Ultra Lounge Halloween Party, 2009

During her most tumultuous year yet, Rihanna came out clawing last year in this animal-print ensemble. Did anyone really expect her to come out as a fairy anyway? RiRi was pissed off and she expressed it through fresh ink, a new album, and a tiger costume. All of which were pretty grrrreat!

Where, Year: At home, 2010

While our minds aren't reeling from the overwhelming originality of this "sexy animal" costume, you have to give her credit for how effing hot this is. It's like, thanks for showing us the exact outline of the curves that made us fall in love with you and your body years ago. This was just last year, too. It's going to take a lot for the newly married socialite to top herself this Halloween.
