Still don’t know what you’ll wear Oct. 31? From an out-of-work Big Bird to Romney’s binders full of women and Mama Snooki, there are plenty of topical Halloween costumes for last-minute trick-or-treaters. Clockwise from top left: AP Photo; Getty Images (3) Ever since Mitt Romney threatened to cut funding for PBS in the first presidential debate, Big Bird and his questionable job security have been a hot topic. From countless memes to appearances on Saturday Night Live, Big Bird has been everywhere lately. He’ll certainly be a popular choice this Halloween, so if you’re planning on dressing up as the giant Muppet, be sure to get your hands on a costume before they’re all sold out! Matthew Peyton/Getty Images Vice presidential hopeful Paul Ryan has been doing everything he can to rally support for Mitt Romney. But the Wisconsin congressman turned heads for a different reason when pictures of him pumping iron leaked. This costume is fairly easy to pull off: just wear a gray T-shirt, basketball shorts, a backward red baseball cap, and earphones, and carry around some weights. Also, tell everyone you meet that you can run a marathon in less than hours. Tom Williams Cyclist Lance Armstrong has been making headlines for all of the wrong reasons for the last couple of months. After the U.S. Anti-Doping Agency accused him of using performance-enhancing drugs, Armstrong was stripped of all of his titles, including seven Tour de France victories, and was banned from cycling for life. So grab a cycling uniform, a helmet, a prop syringe, and, of course, a Livestrong bracelet. Voilà, you’re Lance Armstrong! Mark Gunter/AFP/Getty Images One of the most memorable lines from the second presidential debate was Mitt Romney’s “binders full of women.” The phrase quickly caught fire in the Twitter-sphere and prompted the creation of Facebook pages and Tumblr accounts. Ladies can get a little more creative with this one by fashioning a large binder to become a woman in a binder, while guys can dress up as Romney carrying a few binders full of women with him.

In the final debate, Mitt Romney criticized the size of the U.S. Navy and said it has fewer ships than at any point since 1917, to which President Obama responded: “We also have fewer horses and bayonets.” The two-person horse suit is always a classic Halloween costume, and there will probably more than a few this year. Don’t forget to bring your bayonet! Ryan Mcvay At the 2012 London Olympics, all eyes were on Ryan Lochte. (Let’s face it, Michael Phelps is so 2008.) You can either go with a tracksuit or a Speedo if you’re feeling confident, as long as you also remember to wear a medal or two. Just don’t forget to stumble over your words and talk in a bro-ish manner all night long, and you’ll be a perfect Lochte. Adam Pretty/Getty Images There are a couple of directions you can go with this one. You could go with camouflage or a nice suit. The real key to pulling off the perfect Harry is how you act. The first step is to find the guy dressed up as Ryan Lochte. The second step is to get absolutely smashed together. Bonus points if you challenge Lochte to a race in a swimming pool or if you end up naked by the end of the night. Stefan Rousseau - WPA Pool/Getty Images Toddlers and Tiaras star Honey Boo Boo got so popular that TLC decided to give her and her family their very own spin-off show. And just like that, the young diva became America’s newest guilty pleasure. The best way to pull off the Honey Boo Boo look is to wear a pageant dress and a plastic tiara, and spout gibberish all night long. John Bazemore The Snooki name will live on—Nicole Polizzi gave birth to her first child late last summer. For Mama Snooki, you can always dust off that old Snooki outfit that you wore on previous Halloweens and simply add a baby bump to it. But the best way is to get a baby (doll, of course) and decorate him with some bling and a nice spray tan for that iconic Jersey Shore look. D Dipasupil/Getty Images The K-pop singer Psy has become an overnight sensation, thanks to the viral music video for his song “Gangnam Style.” Psy has made appearances at the VMAs as well as Saturday Night Live and will likely be a very popular Halloween costume this year. So grab a blue jacket, a bowtie, and a pair of shades, and get ready to dance all night long. Warning: if you do decide to dress up as Psy for Halloween, make sure you learn the dance first. Nobody wants to see a Psy who can’t do Gangnam Style. Frederick M. Brown/Getty Images Move over, Evel Knievel. There’s a new daredevil in town, and his name is Felix Baumgartner. Baumgartner caught the world’s attention this month when he set the world record for highest base jump, leaping from 24 miles high and breaking the sound barrier. For this look, get yourself a space suit costume, slap a couple of Red Bull stickers on it, and jump off everything in sight. Balazs Gardi /Red Bull Stratos/Content Pool via Getty Images Clint Eastwood got a lot of attention for Republican National Convention speech, but we all know the real star of the show was the empty chair he scolded in place of President Obama. The best way to pull off this costume is to wear a nice suit, get a gray wig, and yell at all the empty chairs you can find. Mark Wilson/Getty Images The NFL replacement refs have been gone for a while now, but that doesn’t mean you still can’t have a little fun with them for Halloween this year. Get your hands on a ref uniform and make sure you’re equipped with a yellow flag and a whistle. Prepare to annoy your friends by calling penalties on just about everything. Don’t worry, you won’t need any reasonable explanation for doing so. Ezra Shaw/Getty Images
