In the elegant, exclusive shot, Jenner accentuates her long-sleeved, black-and-white dress and voluminous curls with a long gold necklace, showing off the trademark style for which she's come to be known since making her debut on the cover of Vanity Fair earlier this summer.
Promos for the eight-part docu-series, which will follow the former Olympian's life post-transition, have shown Jenner hitting the tennis court, mentoring transgender youth and, of course, building her new wardrobe.
Jenner recently received the Arthur Ashe Courage Award at the ESPYs, where she made headlines for her powerful and emotional acceptance speech, not to mention a full-fledged Versace moment.
The reality star's style streak didn't end there – she's been spotted wearing everything from red print dresses and white brim hats to some serious leather as she introduces herself to both her community and the world.
