It’s almost Halloween—you know, that time of year when your colleagues and friends silently judge you on your creativity and craftiness. Instead of breaking out your trusty Freddy mask, vampire teeth or witch hat, change it up with these cheeky-sarcastic IT-themed costumes that take little to no effort.

Internet of Things

Wear a net and attach random things to it.

White hat / black hat hacker

Put a white or black hat atop your head and bring a kid’s toy machete (make sure it is very visibly a toy— you don’t want to get HR involved).

Big Data

Are you the tallest person in your office? Good for you! Get a name tag and write “Data” on it.

Social media

Attach wax lips to magazines and newspapers and adhere them to your shirt.

Java engineer

Dress up like your favorite Starbucks barista (green apron, hipster accessories) as they ‘engineer’ your java every day.

.NET developer

Carry around a fishing net with film negatives inside of it. Of course, this only works if your coworkers are old enough to remember developing film.  

Front-end developer

women wear film negatives on front and back for front and back end developer costumes 

Tape old film negatives to only the front side of your clothing. Do the reverse and presto, you're a back end developer. 

Body text

a woman wears carat and forward slash tags for a body text costume 

Cut a box in half diagonally so you have greater than / lesser than symbols. Attach each to one side of your body like this: < you >

Mad (data) scientist

Wear a white coat, style your hair all wild, get some lab glasses and carry around a calculator.

Cloud engineer

Wear a train conductor’s hat and fill a white trash bag with newspaper.

Identity thief

a masked woman holds licenses and credit cards (identity thief costume)

Dress up like a cat burglar (all black, with a face mask) and carry a clear bag with your driver’s license or ID card, credit cards and insurance cards.

Information security

a woman wearing encyclopedia pages stands next to a security guard (infosec costume) 

Find an old dictionary or encyclopedia (remember those?!) and rip out the pages. Tape the pages all over your outfit and ask to see people’s IDs if they want to enter your office.


costume: a woman stands behind a painted 'firewall, which a coworker tries to get past 

Find a large piece of cardboard or paper, paint flames on it and stick it to the front of your door. No one can get past your firewall, so you’re free to work the day in peace!

Steve Jobs

Black turtleneck, jeans, glasses and a discerning expression.

Stack Overflow

man with paper popping out of clothes dresses up as Stack Overflow 

Position pieces of paper so they’re coming out of your collar, pockets, pant legs, etc.
