Last-Minute Costume Ideas Based on Your Favorite Class

Halloween may be only a few days away, but you still have plenty of time to throw together one of these school subject-based costumes and impress your friends!

Looking for an educational Halloween costume? Look, it may not seem the most exciting, but these type of costumes can be really fun and creative. Do you have a Halloween costume contest at school? These subject-related costumes for Halloween could be great for that. They’re simple enough to make at home and creative enough to win any costume contest. Depending on your favorite class, here are some easy Halloween costumes to consider! 

Costumes for aspiring scientists

  • A skeleton: Students in science courses, especially biology and anatomy, study various human systems. The skeletal system is the perfect Halloween costume. Maybe for extra credit, you could even label every bone. 
  • Bill Nye the Science Guy: Dress as everyone's favorite science hero with a simple blue lab coat and red bow tie. 
  • Mad scientist: It’s a classic for a reason. Use a plain white lab coat, a crazy-haired wig, and some test tube props to complete the look. 
  • Amelia Earhart: Find a leather jacket, scarf, boots, goggles, and maybe a cardboard airplane, and you’ll be flying high like the pilot herself. 
  • Outer space: This is perfect for a big friend group. Your costumes can include the sun, moon, and stars as well as all the planets. 
  • A robot: Everyone loves a cardboard robot costume. Use boxes, pipe cleaners, and paint for this creative STEM look. You could even take it to the next level with LED lights. 
  • An astronaut: Any orange or white jumpsuit with a NASA logo sticker works for this one.  

Costumes for math lovers

  • Pumpkin Pi: A pumpkin costume with the Pi symbol will do the trick for this punny costume! Make sure to memorize as many Pi digits as you can just to impress people.
  • A calculator: Another simple cardboard-based costume that only requires you to add some numbers and operation signs. Carry a math textbook with you as well and solve some equations.
  • A Rubik's cube: Make this complex puzzle costume out of a cardboard box and some paint.
  • Sudoku: Attach a poster board of a Sudoku puzzle to yourself for an unsolvable costume. You could even carry around some markers and have friends fill in numbers as the night goes on.
  • Math symbols: Grab three friends and do a group costume as the four main mathematical symbols: addition, subtraction, multiplication, and division.

Costumes for history buffs

  • Rosie the Riveter: Represent American women with a blue jumpsuit and red polka dot head wrap. We all know the poster! (Oh, and make sure to show off those biceps as often as possible.)
  • A Salem witch: All you need is a plain black Puritan dress, an oversized white bonnet, and a broomstick. Witches are a classic Halloween costume, but you can make it specific by adding the historical touch.
  • Benjamin Franklin: A jacket, cravat, bifocal glasses, kite, fur hat, and a white wig will have you inventing all night.
  • Cleopatra: This Egyptian costume is a classic and can be found at costume stores just about everywhere, so you don’t even have to worry about making it yourself. 
  • Queen Elizabeth: Thrift shop for a big ball gown, chemise, corset, stockings, neck ruff, and wrist ruff, then do your hair in an updo for this perfect Elizabethan costume.
  • George Washington: A high collar Victorian shirt, regency coat, beige pants, beige vest, white hair wig, riding boots, and a tricorn hat is what you’ll need for this costume. You could even get some fake wooden teeth to really be historically accurate.

Costumes for bookworms

  • Nancy Drew: Dress up as the iconic teen sleuth with a plaid skirt, headband, and polo T-shirt. For props, you’ll definitely need a book, cross-body bag, and magnifying glass. 
  • Arthur: A yellow sweater, blue jeans, big ears, a red backpack, and large glasses are all you need to dress up as the iconic cartoon character that taught us having fun isn’t hard when you’ve got a library card.
  • Edgar Allan Poe: Dress up as the macabre American poet and author with a white button-down shirt, a chiffon scarf, a Victorian frock coat, black pants, black dress shoes, a fake mustache, a feather pen, and—of course—a stuffed raven. 
  • Sherlock Holmes: Love solving mysteries? Dress like Sherlock Holmes with a white dress shirt, black slacks, black dress shoes, a trench coat, a pipe, a magnifying glass, and a cap. And don’t to forget to respond to questions with “Elementary, my dear Watson” at least a few times.
  • Spelling Bee: Were you ever a spelling bee champion? Recreate that with a black and yellow striped shirt, wings, and antenna, then carry around some cut-out letters that spell your favorite vocab words.

CollegeXpress has helped me tremendously in my college search in narrowing down the schools I’m interested in. Using the college search tool, I was able to narrow down my choices to schools that matched what I was looking for. I also used CollegeXpress for their scholarship search, which helped me find scholarships that I meet the requirements of.

I love the site CollegeXpress; it has been very helpful finding colleges and getting them to send me information. It has also been very, very helpful with finding tons of scholarships. Also, I told many of my friends about it and they love it as well!



High School Class of 2021

CollegeXpress really helped me by letting me know the colleges ratings and placements. They gave me accurate information on my colleges tuition rates and acceptance. They even let me know the ration between students and faculty and the diversity of the college. Overall they told me everything I needed and things I didnt even think I needed to know about my college and other colleges I applied for.



High School Class of 2022

CollegeXpress has provided me with tips that were for college students, but as a high school junior, they were still very useful. Not only that, it also gave me an idea of what to expect when it comes to going to college or already being in college. I want to say thank you to CollegeXpress, and I hope you continue the wonderful tips until I hopefully get into college and throughout my college journey.
