The overjoyed girls of UCLA's sorority Delta Nu, led by Margot, Serena, and Pilar, celebrate the imminent engagement of Warner Huntington III to their blonde sorority president, Elle Woods, who is fretting over finding the perfect dress for the occasion. Once she acquires her dream dress, the girls send Elle off to dinner with Warner, where he tells Elle that he needs someone more serious and breaks up with her. Elle is devastated and sulks for twelve days but comes up with a plan to win back Warner after seeing a picture of his brother's fiancée:. She decides to chase Warner to Harvard Law School to show him that she can be serious. With help from Delta Nu sister Kate, Elle studies for the LSATs, missing all spring semester parties in the name of love. In place of writing a personal essay, Elle bursts into the Harvard admission offices with Margot, Serena, Pilar, a squad of cheerleaders and the entire UCLA marching band to prove that she is Harvard material. Despite first being turned down, she is ultimately accepted after revealing that she's motivated by love.
Elle's snobby classmates disapprove of her attire, and the only person who is willing to help her out is the law teaching assistant, Emmett Forrest. However, he cannot protect her in class with the blood-thirsty Professor Callahan. Callahan kicks the under-prepared Elle out of class at the suggestion of her classmate Vivienne Kensington, who happens to be Warner's new girlfriend. This tragedy summons the apparitions of the sisters of Delta Nu, who, acting as a Greek Chorus visible and audible only to Elle, tell her to stay positive, and suggest ways of winning Warner back. Elle, deciding that being blonde is the problem, decides to become a brunette. She heads to the salon The Hair Affair, where she meets beautician Paulette who tells Elle that when she is down, she puts on her favorite CD, and dreams of Ireland. At the Hair Affair, Vivienne gives Elle a surprise invitation to a "costume party". Paulette sends Elle off with a costume for the party, her positivity and blonde hair still intact. If laughter is what you are looking for then Legally Blonde tickets can fulfill that desire.
