Fans of The Handmaid’s Tale, this one is for you. The Testaments, the sequel based on Margaret Atwood’s book set after the events of the original story, is arriving on Hulu on April 8, and I can assure you it’s just as chilling and powerful! Starring fresh faces Chase Infiniti (One Battle After Another‘s budding breakout) and Lucy Halliday, the dystopian drama follows two teens, Agnes and Daisy, who—in the halls of Gilead’s elite preparatory school where the focus is teaching its young girls how to be submissive wives—form a bond that will change the course of their lives.

Following stops in Paris and London, the show culminated its global press tour in Los Angeles with a lavish premiere complete with purple carpet and students of Aunt Lydia’s school. Before the festivities kicked off, series regular Mabel Li—who plays Aunt Vidala, one of the school’s literate and brutal authority figures who train the girls to accept Gilead’s oppressive dogma—invited Who What Wear into her getting-ready suite for an exclusive peek at her simply glamorous Givenchy look.

Firstly, what was the vision/mood you and your stylist Enrique Melendez had for The Testaments’ Los Angeles premiere?

My mood board was very high femme, romantic shapes, and lots of color. I felt like I had done a lot of black recently on the red carpet, but [the] joke’s on me! When we tried this beautiful, elegant Givenchy dress and it fit like a glove, we both knew it was irresistibly the right choice. It exudes effortless glamour. I just love wearing black—what can I say?
