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 video game hotties and comic book characters, but let's start with some of our favourite badass women from the worlds of horror, sci-fi and geeky film and TV.
Hit Girl from Kick Ass
She's the awesome purple haired badass from the Kick Ass movie and although we might not be able to wield weapons and do backflips like she can, we're happy to spend a night as a super hero who curses like a sailor. Tip: Get one of your male friends or boyfriend to dress up as Kick Ass. Available from Angels Fancy Dress for £52.99.
