I probably watched Jim Henson’s “Labyrinth”—starring a young Jennifer Connelly opposite the rawtha formidable one-and-only David Bowie, who played Jareth, the intimidating Goblin King—approximately 100 times when I was a kid and that’s no exaggeration. You better believe Bowie brought his signature sexy androgyny to the table and let’s just say it made a very young lady feel kinda funny inside. Is it weird to dress up as your childhood crush? Nah, but maybe it is a little kinky…

Halloween is the perfect time for a little gender-bending. And Sherlock Holmes is one of the best fictional detectives making a resurgence this year with a new movie, so why not combine the two for your costume? All you need are a few classic menswear pieces that can be pilfered from your dad’s closet, thrifted, or purchased (details after the jump).

Sure, Serena van der Woodsen is supposed to be the talk of the town, but we’re more interested in Blair Waldorf’s prep-school style. This costume has all the naughty school girl appeal with a touch of Upper East Side class. An added bonus? Each piece is really cute and completely re-wearable! Get the deets, after the jump.

It’s no wonder Lady Gaga has reportedly gone bankrupt four times because quite a bit goes into her extravagant everyday looks. Homegirl loves her crazier-the-better accessories! After the jump we’ve got the deets for how to get the perfect Lady Gaga costume with things possibly in your closet already and items you could totally wear again (either with more clothing or while role-playing).

What’s that you say? You didn’t sit front row at a ton of fashion shows in September? How embarrassing for you. Disguise the shame for one evening by dressing as an “It Girl.” We can show you what to wear, but you’ll have to figure out how to do that bored expression on your own.

That evil Gargamel created Smurfette out of clay in order to create chaos at the all-dude Smurf village. Too bad the Smurfs don’t have much going on in the libido department, and instead of competing over her, they took her in as one of their own. After years of rocking semi-slutty Halloween costumes, I’m excited to be Smurfette this year cause she’s cute and sweet and not at all tarty. All it takes is blue face paint, a blonde wig, a white hat and matching dress, and voila, you’re ready to sing “La la la la la la la.”

If the universe were a fair place, the Balloon Boy caper would blow over by Halloween (har, har). But we all know we’re probably stuck with this kid for a while, so why not go trick-or-treating this October 31st dressed as the most famous 6-year-old on the planet, Falcon Heene? All it takes is a big flying saucer-shaped helium balloon and the twinkle of adventure in your eye!

Remember the Eloise books by Kay Thompson about the mischievous child who lived in New York City’s Plaza Hotel? While you may have loved them as a kid, envision Eloise as a grown-up and all of a sudden she’s a sexy character to dress up as for Halloween—schoolgirl skirt, knee-highs, playful attitude (plus, you can’t ignore the fact that she lives in a high-class hotel, wink wink). You can keep the look cute by playing up the hair ribbon and wearing some innocent ballet flats, or add some extra vixen with bedhead hair, an extra button undone and slutty pumps.

Careening through life high on drama is best left to the ladies of “The Real Housewives of New Jersey.” But ripping off their Jersey girl style just for one night will do your bubbies proud! Lucky for you, it’s as easy as making a trip to my fair state’s biggest temple of worship (that’s “the mall,” for those of you in the other 49 states). Your instructions? Find something that clashes, find something else that clashes, press on your fake nails, and poof! You’re ready. But ... but ..., you might be thinking, zebra print and leopard print together? Really? Yes. Trust us. New Jersey‘s state motto is “go big or go home!” So grab your copy of Cop Without A Badge, and check out our picks.

The other day I was walking down the street wearing a shirt with a frilly collar and black skinny jeans, and, suddenly, it hit me! If I put on a cropped jacket, some red knee socks, and carried around a red cape or blanket, I could fight bulls like there’s no tomorrow. Now, if only I knew someone with a bull costume, my matador ensemble would truly be complete.

If you’ve ever wanted to be truly feared, we’ve got the costume for you. We’re not talking “scary” in the way that zombies or pre-Twilight vampires are. That’s child’s play. We’re talking grown women (and men) crying in closets in your wake. For that kind of terror, Vogue editor Anna Wintour is your only option.

Amelias are hot s**t right now. There’s me, of course, and then there’s Amelia Earhart, the legendary female aviator who will be immortalized in a movie starring Hilary Swank later this year. Amelia’s style was already super fierce and I love a costume that allows me to buy pieces that I could wear again. Check out how I would rock her high-flying style on the cheap(ish), after the jump, but know you could always spend more on some of these pieces so they last a lifetime.

Didn’t you just love to hate Maryann Forrester in season two of “True Blood”? Author Charlaine Harris has one helluva imagination, but it was creator/executive producer Alan Ball who brought Maryann to life. Even though she was a rather annoying villain (surprisingly, though, she was less annoying than Sookie Stackhouse), none of this season would have been possible without Maryann’s maenad craziness. So why not celebrate “He who comes” by dressing like his bride for Halloween? Just remember to periodically raise your arms and quiver? How to get the look, after the jump!

We can’t help but be fascinated by Sid Vicious’ ill-fated (not to mention ill-mannered) girlfriend. She was kind of like the Courtney Love of her time, except way less rich, famous and, if you can believe it, even more tragic. To get in the mood, blast Never Mind The Bollocks, watch “Sid and Nancy” on repeat, and try some of these accessories on for size.

With Tim Burton’s psychedelic version of “Alice in Wonderland” in the works, I’ve gotten newly excited about following a white rabbit down a rabbit hole. I don’t really want to be Alice cause she’s booooring, so I think I’m gonna be the Queen of Hearts this year. It’s a simple getup to put together. Get a black and white dress—I’ll spend more on a super cute one I can wear any time of the year. Add heart accessories in red and black, plus a crown and a scepter, which you can make out of tin foil. Voila. You’re ready to go around screaming, “Off with your head!”

Think of Julia Child and the word “sexy” might not come to mind. But then think about all you could do if she were suddenly a sexy Halloween costume. Imagine a short, coquettish apron to show off legs. And a spatula to punish naughty trick-or-treaters.

Itching to dress up like a style dah-ling this Halloween? Dear old kooky Karl Lagerfeld is the obvious choice, but who wants to be obvious on arguably the most important fashion day of the year? Trust me: heads will turn if you arrive at your Halloween fete dressed as classic Coco herself. We prefer the older, established Coco Chanel, whom we imagine left a trail of heaven-sent No. 5 perfume in her wake, so we looked to Shirley MacLaine, star of Lifetime’s “Coco Chanel,” for inspiration.

I bought a long, red trench at a thrift store a couple years ago, and, without fail, I get called Carmen Sandiego every time I wear it. Dressing up as your favorite educational villain is simple if you already own a red trench—or want to buy one to wear on days other than Halloween. And if you’re not into forking over 50 bucks for a coat you’ll wear once, the Salvation Army is always a good place to start your search.

Rachel Zoe‘s large-sunglassed visage has become a ubiquitous image. Her tent dresses are recognizable from yards away. And that mane of wavy blond hair has been copied by Midwesterners and starlets alike. Why not add to all the Zoe worship on Halloween by being her? But you’ve kind of got to take it to the hilt. Here’s how ...

With the Spike Jonze movie opening this month, the book and film’s child hero is likely to be one of this year’s most popular costumes. But you don’t need to run out and buy Opening Ceremony’s $600+ costume. I’m going to keep my hands exposed and paint my nails silver, and added a little more whimsy with a feather crown from Etsy. You could also buy posterboard from an art supply store and cut your own crown. As for this wolf onesie? I plan on wearing mine around the house year-round.
