The sun is setting on Halloween night and you are about to get cozy with your Netflix scary movie marathon when suddenly, you get invited to an awesome Halloween party you just can’t pass up. Since you weren’t planning on going anywhere, you are out of a costume. Luckily, finding a last-minute costume is as easy as perusing through your bookshelf.

“Twilight” Vampire

This costume is easy as it only requires one must-have item: glitter. Throw some glitter all over yourself and you instantly become one of Stephenie Meyer’s sparkly undead. The rest of the costume is up to your performance. If you want to go as Edward , tell every girl in the room you’ll die if you can’t be together. If you want to go as Alice, tell people their “futures” as you see fit. If you don’t have glitter but do have a furry Fido friend, write “Jacob” on your dog’s collar and say “Edward” in desperation every few seconds, and you will be the spitting image of Bella Swan herself.

Call Me Ishmael

Take a page out of “The Office” character Jim Halpert’s simple Halloween costumes and get yourself a blank name badge. But instead of writing your own name, it should read: “Hello, my name is Ishmael.” Not only is it cheap, but it will start a great conversation when you inevitably have to explain it’s in reference to one of the most famous opening lines in history, taken from Herman Melville’s “Moby-Dick.”

“The Giving Tree”

If you have time to make a Wal-Mart run before you need a costume, you can pull off this childhood classic. You will need: a brown shirt and brown pants, a green wig or hair dye, your favorite Halloween candy and something to put it in. When you arrive at your destination, give out the Halloween candy in a reverse trick-or-treat fashion and everyone will love you for the free sweets, even if they don’t get your costume at first glance.

Harry Potter Post-Grad

Want to be something truly scary this Halloween? Give your classic “Harry Potter” costume an upgrade by mixing your Gryffindor tie with your best business casual outfit. Slick your hair back, put on a pair of glasses — or draw them in with eyeliner if you have to — and draw a lightning bolt on your forehead. Hand out a “resume” listing your education from Hogwarts School of Witchcraft & Wizardry, your O.W.L. and N.E.W.T. scores, special skills such as vanquishing Lord Voldemort and, of course, top it off by signing it as “The Boy Who Lived.”

“Fifty Shades of Grey”

Get your mind out of the gutter because no whips or handcuffs will be a part of this easy costume. Find a store that sells paint and take some of its gray-scale paint swatches. Adhere them to a shirt of your choice — gray would clearly work best, if available — and you can literally depict the title of this best-selling, erotic book.
