Blue stocking

Nerdy girl who doesn't bother with fashion or hair styling and make up, sometimes to the point of childish lack of dress sense. Originates in the 18th century where the 'blue' wool stockings were casual, laid back options as opposed to expensive silk ones in ever-changing fashions. The 'blue stockings' were scholarly women who were too busy engaged in improving their minds to worry about constantly updating their wardrobes. Like 'nerd' and 'boffin' this term is a social stereotype for what is actually a trait of Asperger's Syndrome/autism: the lack of awareness of social cues and trends such as fashion, the desire for comfortable dress and just finding studying more interesting than expensive dress.
