Last year we wrote up our 10 Girl geek Halloween costume ideas and judging from how many of you have been visiting that feature over the past few weeks you're going to be taking Halloween very VERY seriously this year.
So, instead of pulling together a general girl geek list we've split up the Halloween costume ideas into categories, like badass women from the worlds of film and TV, our favourite comic book heroines and villains and video game hotties.
If the thought of baring your tummy on Halloween or playing up to the slut stereotype makes you feel ill, then we've also got some options for you, like this yellow Angry Birds costume packed full of LOLz. We also recommend you get the cartoon hand gloves too to complete the look. Available from Fancy Dress Ball for £44.99.
