Dear Deer

Dress up on Halloween as a deer with a simple costume made from things you mostly already have on hand. Wear a brown or gold dress and pin a piece of white felt or fur to the front. Add an ear headband and glue on some sticks for antlers. You can draw a nose on your face with eyeliner.

Video Conference Dude (or Lady)

In the age of Zoom meetings and online conferences, there's something hilarious about seeing a person dressed professionally on the top half and wearing boxer shorts or pajama pants on the bottom. You can shop your closet for this costume. Simply choose your best suit or dressy top and pair it with something equally informal and unprofessional on the bottom. Carry a laptop or wear a headset to make your meaning clear.

Bubble Tea

If you love drinking bubble tea, you can make yourself a bubble tea costume in no time. You just need a white dress or outfit and a bunch of black pom-poms. Glue the pom-poms to the bottom section of your outfit. Then cover a paper towel tube in tan or striped paper and attach it to a headband as the straw.

All-Seeing Alien

You don't need a green mask to be an alien for Halloween. In fact, you can make your own eye mask that will make everyone laugh. All you have to do is glue tons of fake eyes to a regular plain eye mask from the craft store. Pair it with perfectly normal clothing, and it's a winner.

Pink Flamingo

Opt to be the ultimate in lawn kitsch by dressing up as a pink flamingo. This outfit works great for women, but it's just a little more amusing if you're a dude. Start with orange tights for the legs and add any kind of pastel or pink shorts or skirt. Then wear a pink hoodie or furry jacket, a beak, and maybe some sunglasses. This is a great last-minute option if you need something awesome in a hurry. Remember to stand on one leg!

Electrocution Victim

This is a funny costume you can make yourself, and it doesn't even require a trip to the store. Use hair gel or pomade to spike your hair up so it looks like you were electrocuted. Cut the end off an old extension cord (make sure you've unplugged it first). If you don't want to sacrifice an extension cord, just carry your toaster around.

Toy Doll

You don't need special makeup skills or a ton of expensive gear to create an awesome doll costume. Simply place your hair in two pigtails, add some bright makeup to your cheeks and eyes, and wear the most frou-frou clothing you can find. Think tutus, full skirts, and patterned dresses. Add a pair of Mary Janes and some tights, and you'll look the part.

Creative Vampire

When it comes to adult Halloween costume ideas, the classics are classic for a reason. Still, you can change things up a little for a creative take. You can always wear the classic vampire cape, but there's no reason to limit yourself to that. Instead, dress in clothing you already own, preferably black, silver, grey, or red. Then add some fangs and some dramatic makeup. You can even put on a wig for a really cool look.
