Not many women style their dyed raven hair in the pigtails and bangs she wears onscreen as forensic specialist Abby Sciuto not to mention offscreen when the Los Angeles weather is hot and sticky.

A lot of that had to do with her dedication to Abby, a character conceived by NCIS creator Donald Bellisario to A demonstrate that women can excel at math, science and computers and handle themselves around dead bodies and B challenge the stereotype that all tattooed goth girls dressed in black are bitchy, needle-marked perps. Abby is proper nice.
