On Friday, a new preview Caitlyn Jenner's docuseries [1] was released, giving us a peek inside her world. "It's going to be quite a journey," she says. Caitlyn only made her debut on June 1 with her stunning Vanity Fair cover [2], but she's already an expert when it comes to makeup and clothes. In the first promo clip [3] of I Am Cait, she gave the world a glimpse at her stunning fashion sense. In addition to doing her makeup at a stocked vanity, she also rocks a chic pair of sunglasses and a classic hairdo while driving around with a group of friends.

Earlier this month the world got a behind-the-scenes look at Caitlyn's first major photo shoot with Vanity Fair, where she rocked multiple stunning looks [4] for the July issue. Keep reading to see more beautiful photos of Caitlyn, and then watch the preview clip in the link above. I Am Cait premieres on E! on Sunday, July 26, at 9 p.m.
