The music video for the song was shot in February 2014 in Los Angeles and premiered on 4 March 2014, on Vevo. Directed by Director X, the visuals are inspired by the 1995 American coming-of-age comedy film Clueless, with Azalea playing Beverly Hills socialite Cher Horowitz and XCX as Tai Frasier (as well as a redheaded rival filling in as Amber, and the brief character appearance of Dionne and Murray lookalikes) in a remake of the cult classic originally starring Alicia Silverstone, Stacey Dash, Elisa Donovan and Brittany Murphy. On 4 March, behind the scenes footage for "Fancy" was released shortly before the music video premiere. Over 250 extras were individually styled, taking over two weeks to prepare the styling for the video. The video shoot was the very first time Azalea and XCX met in person.
Many scenes in the video are remakes of key Clueless scenes, with outfits designed to channel the look of the film's clothing, but with a slight update. Like Clueless, the music video for "Fancy" was shot in Los Angeles' Grant High School.
The video opens with Azalea in her wardrobe finding the perfect outfit for a speech at school, using a tablet computer, similar to the protagonist of Clueless Cher Horowitz. After a scene with some cheerleaders, the video moves in the schoolyard; there, Charli XCX and Azalea are sitting on a table, with the former singing the hook. The video later includes a tennis lesson, with Azalea and others dancing close to a chain-link fence. Azalea with two other characters are seen driving in the highway; the characters of the best friend and her boyfriend are inspired by the role of Dionne Davenport and her boyfriend Murray. The video shifts to a modern version of the Christmas "Val party" from the movie, where the two protagonists arrive with their convertible. The video ends with Azalea and XCX in the school.
