Mona May is the costume designer of the ’90s cult classic film Clueless. In this episode, Who What Wear Senior Fashion and Social Editor Tara Gonzalez sits down with May to mark 30 years after the film’s release and to look back on the movie’s instantly recognizable fashion. May tells us about how she turned herself into a fashion “detective” when sourcing pieces for Clueless and how she mixed high and low fashion to tell a story and stay within her modest budget. She dishes on what it was like fitting Alicia Silverstone for Cher’s iconic yellow plaid suit and the story behind the giant hat Stacey Dash wears for Dionne’s matching look. Plus, May gives us a peek into her new book, The Fashion of Clueless, which features pages from her sketchbook for the movie and exclusive interviews with the cast.
