Last Minute Halloween Costume Ideas
Why Last Minute Costumes Rock
Let’s face it – I’m a pro at procrastination. But that’s okay! Last minute Halloween costumes are the best.
First off, they’re super budget-friendly.
You can raid your closet or grab a few cheap items from the dollar store.
No need to splurge on pricey pre-made outfits.
DIY costumes are way more fun too.
It’s like arts and crafts time for adults!
Plus, homemade costumes always have the best stories behind them.
“Oh this? I threw it together with some cardboard and duct tape an hour ago!” Instant conversation starter.
Best of all? You don’t have to stress about planning weeks in advance.
You can change your mind right up until Halloween night. Freedom!
So embrace the last minute costume, my fellow procrastinators.
It’s all about having fun and not taking ourselves too seriously.
Now excuse me while I go turn this lampshade into a hat haha.

Ghost Costume
I love a good ghost costume.
It’s super easy to make and always gets a laugh.
Here’s what you need:
- White sheet
- Scissors
- Black marker
Cut two eye holes in the sheet.
Don’t make them too big or you’ll ruin the spooky effect!
Drape the sheet over yourself and voila – instant ghost.
Witch Costume
Feeling witchy? This classic look is a breeze to put together.
Grab these items:
- Black dress or robe
- Pointy hat
- Broom
- Green face paint (optional)
The black dress is the key piece.
If you don’t have one, a dark-colored robe works too.
Pop on the pointy hat and you’re almost done.
Carry a broom for extra witchy vibes.
Skeleton Costume
For a spooky but simple costume, you can’t beat a skeleton.
Here’s what you’ll need:
- Black clothes
- White paint or tape
Put on all black clothes – shirt, pants, and shoes.
Then use white paint or tape to create bones.
Focus on the ribs, spine, and arm bones.
Don’t worry about being exact – a rough outline works great.
Wednesday Addams Look
I love this spooky-chic option!
Grab a black dress and white collar – boom, you’re halfway there.
I like to add some black tights and shoes too.
For hair, two braids are a must.
Don’t forget Wednesday’s signature deadpan stare.
A bit of pale makeup and dark lipstick really sell the look.
If you’re feeling crafty, make a mini Thing hand to carry around.
It’s such a simple costume, but so iconic.
Holly Golightly Glam
Breakfast at Tiffany’s, anyone? This glam look is easier than you’d think.
Start with a little black dress – we all have one, right?
Add some long black gloves and a chunky necklace.
Pop on some big sunglasses and style your hair in a fancy updo. If you can find a tiara, even better!
Don’t forget the long cigarette holder (fake, of course).
Bonus points if you carry a takeout coffee and danish. It’s classy, sassy, and oh-so-Holly.
Super Mario Siblings
Here’s a fun duo costume!
For Mario, grab some overalls, a red shirt, and a red cap.
Luigi just needs green versions.
Add some fake mustaches and you’re good to go!
Mary Poppins Perfection
Supercalifragilisticexpialidocious!
This magical nanny look is easier than you’d think.
Start with a long black skirt and white blouse.
Add a bowtie and you’re on your way.
The key items are a black hat (decorate with some fake flowers), an umbrella, and a carpet bag.
If you can find a little red bow, even better!
For makeup, rosy cheeks are a must.
Don’t forget Mary’s prim and proper posture. It’s a jolly holiday costume that’s sure to bring smiles.

Sailors and Captains
Ahoy, matey! A sailor costume is super easy to pull together.
Start with a striped shirt and blue jeans or shorts.
Add a red bandana around your neck for that nautical flair.
Want to be the captain instead?
Throw on a navy blue blazer and grab a captain’s hat.
Don’t forget to make a paper telescope!
For accessories, I recommend tying a rope around your waist as a belt.
Pin some fake medals to your chest if you’re feeling fancy.
A toy parrot on your shoulder is the perfect finishing touch.
Just practice your “arrr” and sea shanties, and you’ll be ready to set sail.
Mad Scientist Madness
Time to get weird with a mad scientist look!
Start with a white lab coat or button-up shirt.
Mess up your hair for that “I’ve been experimenting all night” vibe.
I like to use colored hairspray for extra craziness.
Grab some thick-rimmed glasses or goggles to protect your eyes from explosions.
Rubber gloves are a must for handling dangerous chemicals.
Carry around some test tubes or beakers filled with colored water.
Bob Ross Bliss
Happy little trees, anyone?
Channel your inner Bob Ross with this chill costume.
Start with a light blue button-up shirt and jeans.
The key is that iconic perm – grab a curly wig or tease your hair if it’s long enough.
Carry a paint palette and brush as props.
I like to cut the palette out of cardboard and add blobs of paint.
A fake mustache completes the look if you can’t grow your own.
Smarty Pants
I love this costume because it’s so simple yet clever.
To make it, you just need a pair of pants and some Smarties candies.
I stick the Smarties all over the pants using safety pins or double-sided tape.
Voila!
I’m literally “Smarty Pants.”
Cereal Killer
This punny costume is a bit darker, but still fun.
Start with a plain white t-shirt.
Then glue small cereal boxes all over it.
The key is to “stab” each box with a plastic knife.
You can splatter some red paint on the shirt and your face for a gory effect.
To complete the look, carry a big spoon as your “weapon.”
It’s a bit morbid, but the wordplay makes it more silly than scary.
Chip on Your Shoulder
For this costume, you need a plain t-shirt and some cardboard.
Cut the cardboard into a large potato chip shape and paint it to look like a real chip.
Then attach it to the shoulder of your shirt.
Add some “chip crumbs” around the neckline for extra detail.
Headbands and Hats
Headbands and hats are my go-to for instant costume magic.
Grabbing a plain headband and hot-gluing on some cat ears – meow!
Or stick a unicorn horn on there for a mythical vibe.
Baseball caps are great too.
I once wrote “404 Error” on a white cap and went as a broken website. So clever, right?
Funky Glasses and Ties
Glasses are a game-changer for costumes.
I’ve got a drawer full of goofy specs – oversized sunglasses, Harry Potter rounds, even some with attached mustaches.
Ties aren’t just for the office.
I’ll wear a bunch of colorful ones and go as a “neck-tie fighter” (get it?).
Or I’ll grab that ugly Christmas tie and pair it with a red shirt for an easy Santa.

Magical Creatures
I’m all about those mystical vibes.
For a quick fairy costume, grab some shimmery makeup, a flowy dress, and stick on some fairy wings.
Bam!
Instant enchantment.
Want to be a unicorn?
Tie some ribbons in your hair, slap on a horn, and go wild with glittery face paint.
It’s silly but oh so fun.
Mermaids are always a hit. Throw on a green skirt, a seashell top, and maybe add some scales with face paint.
From Beyond the Stars
Alien costumes are a blast.
Paint your face green, pop on some antennas, and wear all silver.
It’s out of this world!
For a fun twist, I love a bubble tea costume.
Wear brown clothes, attach some pom-poms as “bubbles”, and make a straw hat.
It’s weird and wonderful.
Another goofy idea is a bubble bath costume.
Stick white balloons all over yourself and carry a rubber ducky. It always gets laughs.
Pet-Friendly Picks
For the four-legged family members, I love a classic hot dog costume.
It’s simple – just a bun-shaped foam piece with a hole for their head and legs. Too cute!
Another easy option is turning your pet into a Beanie Baby.
Just grab a large red heart-shaped tag, write “Ty” on it, and attach it to their collar. Instant 90s nostalgia!
For lazy cats, go with the loaf of bread look.
A cardboard box painted to look like a loaf, with holes cut for the head and paws. Purrfection!
Snuggly Adult Selections
When you want comfy, reach for the trusty t-shirt costume.
Grab a plain white tee and draw on it to become a Dalmatian, a stick figure, or even a Subway map.
Another cozy pick is the classic ghost. Just throw a white sheet over yourself with eyeholes cut out. Easy peasy!
For a bit more pizzazz, a beret and striped shirt combo for an instant French artist vibe. Ooh la la!
Don’t forget the beanie option.
Pop one on and go as a hipster, a fisherman, or even a garden gnome. So many choices, so little effort!
Dynamic Groups
Mario and Luigi are always a hit.
Grab some overalls, colored shirts, and fake mustaches. Boom!
You’re ready to save the Mushroom Kingdom.
For a twist, try Pac-Man and a ghost.
Yellow t-shirt for Pac-Man, bedsheet with eyeholes for the ghost. Easy peasy!
Want something more down-to-earth? Go as lumberjacks.
Plaid shirts, jeans, and toy axes are all you need.
Or be folk singers with acoustic guitars and flowy clothes. You’ll be strumming in no time.

Team Themes
Nerds are a classic group costume.
Grab some thick-rimmed glasses, suspenders, and pocket protectors.
Don’t forget to tape those glasses for extra nerd cred!
For food lovers, why not be a charcuterie board?
Each person dresses as a different item – cheese, grapes, crackers.
Use cardboard and paint to make your food shapes. It’s cheesy but fun!
T-shirts are your best friend for quick group costumes.
Pick a theme like colors of the rainbow or emojis.
Add some face paint, and you’re good to go. Remember, the sillier, the better!
