College Halloween runs on two things: a tiny budget and zero prep time. You find out about the party on Thursday and the party is on Friday. Sound familiar?
Every costume on this list costs under $20, and most cost nothing at all. They are built from closet clothes, dorm room supplies, and one quick thrift store run. Pick one tonight and you are party ready.

Quick Picks
- Zero dollars? The nerd, tourist, and Error 404 use only what is already in your room.
- Going with your roommate? Salt and pepper, plug and socket, and Thing 1 and Thing 2 are made for duos.
- Want laughs? The pun costumes like cereal killer and deviled egg win every funny vote.
- One thrift trip? Cowboy, pirate, and flapper each need a single $5 to $8 thrift find.
- Running really late? Every idea in the closet section takes under 30 minutes.
Did You Know?
College students are the biggest Halloween spenders per person in the country, yet campus costume contests are almost always won by DIY entries. Judges and crowds vote for creativity and humor, not price tags. A clever pun costume made from a $2 t-shirt beats a $60 packaged costume nearly every time.
Before You Start
- Raid your closet and your roommate’s closet before spending a cent. Text the group chat for borrowed pieces.
- Hit the campus thrift store early in the week. The good stuff disappears by Thursday.
- Keep a basic makeup kit handy: black eyeliner, white face paint, and red lipstick cover most looks.
- Charge your phone and clear storage. You will take 200 photos and you know it.
- Bring a jacket or layer into the plan. October nights on campus are cold, and lines for parties are long.
Straight from Your Closet
1. The Nerd
Glasses, suspenders, and an attitude of academic superiority. Done.
Button up a shirt, add a bow tie or suspenders, and tape the bridge of cheap glasses. Slick your hair into a severe side part. Pro tip: carry a stack of textbooks and correct people’s grammar all night for full character commitment.
2. The Tourist
Fanny pack on, dignity off. The tourist is comfortable, funny, and instantly readable.
Hawaiian shirt, shorts, tall socks with sandals, and a camera around your neck. Add a straw hat or visor. Pro tip: unfold a paper map at the party and loudly ask where the bathroom is. People will lose it.
3. Rosie the Riveter
Strong, simple, and done in 15 minutes flat.
Denim shirt with rolled sleeves, red bandana, red lipstick. Flex for every photo. Pro tip: write “We Can Do It!” on a piece of cardboard for a prop that makes the costume obvious from across the room.
4. 80s Aerobics Instructor
Neon, leg warmers, and aggressive enthusiasm. The 80s called and they want you at this party.
Bright leggings, an oversized sweatshirt with one shoulder cut out, and a sweatband. Tease your hair big. Pro tip: lead the room in jumping jacks every hour. You become the party’s entertainment, not just a guest.
5. VSCO Girl
Scrunchies, hydro flask, and “sksksk.” Your freshman year starter pack is now a costume.
Oversized t-shirt, shorts, scrunchie on the wrist, and your reusable water bottle as a prop. Say “and I oop” at dramatic moments. Pro tip: add temporary shell necklaces from the dollar store. The details sell it.
6. Smart Cookie
A pun costume that takes five minutes and a marker.
Wear a graduation cap or a “smart” looking outfit, then tape paper chocolate chip cookies all over your shirt. Write “smart cookie” on a name tag. Pro tip: hand out actual cookies from a bag. You will be everyone’s favorite person.
7. Error 404
The costume for every computer science major and procrastinator.
Plain white t-shirt with “ERROR 404: COSTUME NOT FOUND” written in marker. That is the whole thing. Pro tip: when people ask what you are, just stare blankly and say “page not found.” Minimal effort, maximum laughs.

Dorm-Room Duos and Trios
8. Salt and Pepper
The classic couple costume that works for best friends too.
One person dresses in all white with a big “S” taped on, the other in all black or gray with a “P.” Make shaker caps from construction paper. Pro tip: argue all night about which one of you is salt. The bit never gets old.
9. Plug and Socket
One of you is the plug, one is the outlet. Together you are electric.
The plug wears black with two foam prongs on a headband. The socket wears white with a drawn outlet face on the shirt. Pro tip: spend the whole night trying to “connect.” It is dumb and it works every time.
10. Mario and Luigi
Gaming’s most famous brothers are a duo costume that never misses.
Red shirt and blue overalls for Mario, green shirt and blue overalls for Luigi. Red and green caps with “M” and “L” drawn on. Pro tip: fake mustaches from the party store cost $2 and complete the look instantly.
11. Thing 1 and Thing 2
Dr. Seuss chaos in matching red jumpsuits or red shirts and blue wigs.
Red tops, a circle of paper that says “Thing 1” or “Thing 2” pinned on, and wild blue hair (spray or wig). Pro tip: run everywhere instead of walking. Things do not walk. They zoom.
12. Cop and Robber
One enforces the law, one breaks it. Handcuffs optional but encouraged.
The cop needs dark clothes, a badge drawn on paper, and aviator sunglasses. The robber gets stripes, a beanie, and a bag with a dollar sign. Pro tip: plastic handcuffs from the dollar store linking you together make every photo ten times funnier.
13. Netflix and Chill
The costume your entire friend group already understands.
One person wears a red shirt that says “Netflix,” the other wears blue pajamas that say “Chill.” Carry a laptop or a popcorn bucket. Pro tip: this works great as a trio if someone goes as the popcorn. For dorm room decor ideas to set the scene before the party, check our guide.

Funny and Punny
14. Cereal Killer
The punniest costume in the history of pun costumes.
Tape mini cereal boxes to a plain shirt, splatter them with fake blood, and carry a plastic knife. Write “cereal killer” on the shirt. Pro tip: the smaller the cereal boxes, the funnier it looks. Snack-size boxes from the dining hall are perfect.
15. Deviled Egg
Simple, hilarious, and weirdly cute.
Wear all white with a yellow oval (paper or felt) on your stomach. Add red devil horns and a pitchfork. Write “deviled egg” underneath the oval. Pro tip: carry actual deviled eggs on a tray as a snack. Meta and delicious.
16. Pig in a Blanket
Breakfast food meets cozy bedding. What is not to love?
Wear a pig nose and ears (about $5 for the set), then wrap yourself in a blanket or wear a blanket-print poncho. Pro tip: stay wrapped all night and refuse to take the blanket off. Commitment is the joke.
17. Taco Belle
Disney princess meets Taco Tuesday.
Yellow ballgown-style dress or yellow skirt, then glue felt lettuce, tomato, and cheese shapes around the waist like taco fillings. Add a small crown. Pro tip: hand out hot sauce packets as party favors. Everyone keeps them.
18. Chick Magnet
Stick plastic baby chicks all over yourself and let the puns roll.
Any outfit works. Hot-glue a dozen fluffy chick toys from the craft store onto a shirt or hat, then carry an actual horseshoe magnet. Pro tip: the chicks cost about $4 for a bag. This is peak dollar-store comedy.
19. French Kiss
Romantic, ridiculous, and very on theme for a college party.
Wear a beret and a striped shirt, then tape Hershey’s Kisses all over your shirt. Add a drawn-on mustache for extra French energy. Pro tip: offer people kisses (the chocolate ones) all night. You will make a lot of friends.

Thrift Store Gold
20. Cowboy
One thrifted hat and you are 90 percent done.
Plaid shirt, jeans, boots, and a cowboy hat from the thrift store (usually $4 to $6). Add a bandana around your neck. Pro tip: draw a sheriff star on paper and pin it on. Instant authority, zero effort.
21. Pirate
Argh. The thrift store is basically a pirate supply shop in October.
Striped shirt, dark pants or a skirt, boots, and a bandana or tricorn hat. Add a toy sword and gold hoop earrings. Pro tip: smudge black eyeliner around one eye and talk like a pirate all night. No one will stop you.
22. Fairy
Soft, sparkly, and endlessly customizable from thrifted pieces.
Any flowy dress or skirt works. Add wings from the party aisle (about $8) and glitter on your cheeks. Flower crowns from the craft store finish it. Pro tip: go dark fairy with black wings and dark lipstick if cute is not your thing.
23. Flapper
The 1920s are back, and thrift stores are full of fringe.
Look for any dress with fringe or beading. Add long gloves, a headband with a feather, and pearls. Dark red lips complete the era. Pro tip: learn two Charleston steps from a video. You will own the dance floor.
24. Scarecrow
Cozy, autumn-perfect, and built from flannel you already own.
Plaid flannel shirt, jeans with patches, and straw (raffia from the craft store) sticking out of the sleeves and collar. Draw stitched smile lines with eyeliner. Pro tip: a burlap-textured hat or headband pulls the whole scarecrow story together.
25. Greek Statue
Bed sheet, gold accessories, done. The toga is the original budget costume.
Wrap a white or cream flat sheet toga-style and secure it with safety pins. Add a gold rope belt and laurel leaves made from paper. Pro tip: paint yourself very lightly with white powder and stand perfectly still when people walk by. Then move. You will get screams.

Common Mistakes to Avoid
- Waiting until Friday to shop. Thrift stores get picked clean by Thursday night. Go Monday or Tuesday for the best selection.
- Buying a packaged costume. They cost $40 to $60, fit badly, and three other people will be wearing the same one.
- Forgetting your student ID. Parties, bars, and events all need it. Build a pocket or small bag into the costume plan.
- Skipping the group chat. Nothing is worse than showing up in the same costume as your roommate. Coordinate early.
- Wearing shoes you cannot walk in. Campus parties mean walking across campus. Cute boots that hurt will ruin your night by 10pm.
- No phone plan. Between photos, rides, and finding friends, your battery dies fast. Bring a portable charger.
