When Elle Woods arrives for the first time at Harvard in her hot pink outfit and convertible, one of the students condescendingly refers to her as "Malibu Barbie" as she steps onto the campus. Mattel later released a promotional Legally Blonde themed Barbie doll for the release of Legally Blonde 2: Red, White & Blonde (2003). This movie is also often referred to by fans and audiences as an unofficial live-action adaptation of Barbie as well.
A perfect score on the LSAT exam is 180, therefore Elle's score of 179 puts her in the top 0.1 percent.
Elle Woods was named after Elle Magazine. Amanda Brown, author of "Legally Blonde", the novel on which this movie was based, spent her time at Stanford Law School reading copies of Elle Magazine.
While at Stanford, source book author Amanda Brown wrote letters back home, regarding her inability to fit in with her classmates. Later she made a manuscript based on those letters and sent it to an agent, who was drawn to it because it was the only manuscript submitted written on pink paper - referenced in this movie through Elle Woods' scented pink résumés.
