As a student, Gillies struggled with severe dyslexia. She graduated from New York University with a BFA in film. Gillies is the daughter of Archibald and Linda Gillies.

Gillies landed her first movie role when Whit Stillman cast her as Cynthia McLean in his pioneering independent film, Metropolitan (1990). Other film credits include Finley in Another Girl Another Planet (1992), Alison in I Shot Andy Warhol (1996), Moira Ingalls in On Line (2002), Isabel in Happy Here and Now (2002), and Kathryn in New Orleans, Mon Amour (2008). Prior to her role as Kathy Stabler on SVU, which she played from 1999 to 2011, Gillies appeared in "Bad Girl," an episode of the original Law & Order series, playing Monica Johnson, a young woman who murders an undercover police officer and then undergoes a religious conversion during her trial and is born again. In 2000, she played the role of Alison in the short-lived Fox series, The $treet. In 2021, she reprised her role as Kathy Stabler for one episode during season 22 of SVU; the cross-over episode that launched Law & Order: Organized Crime. The hostile online reaction of SVU fans to her character's death led Gillies to discuss how fandom had changed due to social media. She has since reappeared in flashbacks, most recently in 2025.

She was married to DeSales Harrison, an English professor at Oberlin College, from 1999 to 2005. Gillies married Peter Lattman, an editor at The New York Times, on October 13, 2007. Gillies spends her summers in Islesboro, Maine.
