One idea for a female nerd costume is dressing up as an online meme, such as the hipster mermaid. Women and girls can also dress up as a female version of Han Solo in the "Star Wars" film series to exude a nerdy vibe.
Other costume ideas for nerdy women and girls include female versions of different doctors from "Dr. Who," or they can dress up as their favorite sidekicks, such as Amy Pond. Nerdy women and girls can also dress up as human versions of the TARDIS or as Dalek from the show. Yet another option is their favorite Pokemon from the "Pokemon" series.
