Katy Perry Costumes From Last Friday Night Video

Katy wears huge geek glasses in her music video and your look won't make any sense without them! She is wearing red rimmed nerd glasses so make sure you purchase some for cheap here on Amazon. Make sure you also put some tape in the middle of the glasses to make it look like they're broke!

To complete your Katy Perry look for this Halloween, make sure you purchase these fake braces! Katy Perry is dressed up as a nerd and even wears headgear. I looked online and did not see anyone selling headgear (probably for health concerns) so you might want to make your own with wire. Check out these funny sanitary teeth!

The main costume accessory if you don't have dark brown hair is to purchase a wig or braid piece. In her Last Friday Night video she wakes up with crazy hair so just rat the front bangs up and hair spray the crap out of it! She also has a long braid hanging off her left shoulder. It's easy to braid wigs so buy a cheap one. She has hot pink little hair binders with balls on the ends. You can purchase those for cheap in the little girl section at Target or wherever.
