4 nerdy costumes you can wear this Halloween from stuff you already have

There’s nothing like expecting to not get invited to anything for Halloween only to get an invite to a sweet party at the last second because someone cooler than you couldn’t make it. Not that I would have any personal experience with pity invites…

Of course, the challenge is pulling together a top-notch costume at the last minute. And, being the nerd that you are, you need to show come up with something that will keep your nerd-cred solid in the public sphere.

These costumes are easy to put together even on the shortest of notices, and will ensure no one questions your authority on things like parsecs and video games. We’re making the assumption that you have a few Halloween things packed away from previous costumes, meaning you can put these together with what you already have or just a few easy items that don’t require fighting off all the other last-second Halloween shoppers.
