The simple nerd costume


Thanks to Stranger Things and The Big Bang Theory, nerds are cool again! Good thing, too, because a nerd ensemble makes for an easy last-minute DIY Halloween costume you can pull together using items from your own closet.

Just hike up a pair of jeans à la Steve Urkel from Family Matters, and pair it with a dress shirt with some pens in the pocket.

Then add suspenders, white socks and black shoes, and top it off with this pair of Nerdy Glasses from Rhode Island Novelty, complete with white Teflon tape on the bridge. Voilà: the geek squad has arrived!

Be the Instagram story you’ve always wanted


Live out your Instagram Story fantasies with a totally cool, yet super simple, adult Halloween costume at your next party. Print a blown-up copy of the Instagram logo and pin it to any outfit as part of your Instagram Story.

Whether it’s an exotic vacation you’re dressed for, an extreme sport stunt or the job of your dreams, dress the part and take the shot. Not sure which one to try on for size? You can try on a cute book blogger look with a vintage librarian outfit sourced from your closest. All you need is a pleated or pencil skirt, stockings, tortoise-shell glasses, heels or flats and grab an armful of your favourite books.

Or, grab some ski goggles and poles, pair them with Zodaca’s Knitted Beanie Hat and pose for your chalet chic adventure story.

Tasty grapes, anyone?


Here’s a juicy costume idea for you: hang out by the buffet table camouflaged as your favourite fruit.

For this attention-grabbing costume, all you need is a few packages of coloured balloons and a matching long sleeved shirt paired with pants or leggings to go dressed as a big bunch of purple or green grapes. Fasten as many balloons as you can to your clothes by threading pins through the ends of the inflated balloons.

If you’re feeling extra crafty, you can cut some leaves out of green felt and use a hot glue gun to attach them to a headband. At the end of the night, gauge how much fun you’ve had by how many balloons have popped! If you leave the party looking more like a bunch of raisins, you know it’s been a good night.

The coolest (literally) ice cream costume

Ice cream costume

Be the queen of cool when you walk in with your sweet-as-can be ice cream costume! It’s super simple to whip up—just take a white dress, like the Womens Floral Lace Shift Dress from Charter Club, and tape or glue on Twizzlers and small pieces of coloured felt or pom poms for sprinkles.

For an ice cream sundae costume, cut a cherry from red Bristol board and use a hot glue gun to attach it to a headband. Or, for an ice cream cone costume, roll orange or brown Bristol board into the shape of a cone for your headwear for the night.

It’s a sweet, simple costume everyone will love!

I scream, you scream, we all scream for…

Queen of Hearts costume


Steal the show with this Alice in Wonderland-inspired costume idea. A Queen of Hearts DIY Halloween costume is not only effortless and fun, but it will also give you the chance to get away with shouting “Off with their heads!” whenever you feel like it.

For this look, you’ll need a red or black dress, red and white face paint and red or black heels. If want to take it to the next level, fan out a deck of cards in a circle pattern and use a stapler to create a collar that will make your costume really stand out. Top your ensemble off with this Royal Queen Crown from Forum Novelties, or get crafty and make one yourself with metallic paper, scissors and glue.

Look out, people: the queen has arrived!
