Let’s assemble your nerd outfit. Want to know how to dress like a nerd? It’s easy. Anything goes when it comes to geeky attire.
When my daughter was 10 years old, she informed me she needed a nerd outfit as she was going to be a geek for Halloween and had to dress like a nerd for school.
Yes, the day before Halloween – but as I have learned over the year, last minute Halloween costumes are my speciality. Thankfully throwing together nerd outfits is easy peasy. I was happy to quickly realize that nerd costumes are actually easy to throw together.
How to DIY Nerd Outfits
We headed to Goodwill thrift store to find the perfect nerd outfit.
A few mismatched clothes, a girl scout sash and thick black taped glasses, my daughter had the perfect nerd outfit. Here is a simple way to grab a few things from around the house or at a thrift store for an cheap costume thats extra nerdy.
- Geek glasses – tape thick black rim glasses also comes with a pocket protector!
- Oversized khaki pants – thrift store find
- Tweety bird vest – thrift store find (and she won’t throw it away ARGH!)
- Girl scout shirt – thrift store find
