We predicted Millie Bobby Brown would take over the fashion world [1], and she's starting with a Calvin Klein ad. Shot by Willy Vanderperre, Millie strikes a serious pose for the brand's new made-to-measure service, By Appointment. According to Calvin Klein's Creative Director Pieter Mulier, who works closely with Raf Simons, the 14-piece collection is "driven by character; it's about a woman feeling empowered and being her own person in what she wears."

The Stranger Things [2] actress echoed Pieter and Raf's sentiments by sharing a 'gram of her own, writing, "I am so honored to be a part of this- 'A cast of distinct individuals brings the idea to life: Strength of character is key. Whether famous or unknown, all are treated equally.'"

By Appointment officially launches on April 1 [3], when customers will be able to book appointments at the brand's NYC office. Read on to see Millie's first-ever campaign alongside other famous faces like model Natalie Westling.
