How That Corset Ended Up On Caitlyn Jenner's 'Vanity Fair' Cover

And more from stylist Jessica Diehl's interview with 'Vanity Fair.'

Yesterday, Caitlyn Jenner made her worldwide debut on the cover of Vanity Fair. The woman tasked with styling Caitlyn for her major reveal was Jessica Diehl, Vanity Fair's fashion & style director.

Now that we've all been lucky enough to see the gorgeous Annie Leibovitz-shot photos, Jessica explains in an interview—with VF, of course—how they kept things so secret, how they decided on the outfit for the cover, and more.

Considering the top-secret nature of the shoot, Jessica explains that she couldn't style it like she normally does—she couldn't just call up a designer and ask to borrow clothes, she had to go into stores and buy stuff off the rack. Before going into the stores, though, she and Caitlyn decided on one thing—"to focus on style over fashion."

As for how they landed on the white corset for the cover, Jessica says, "there was a stripped-down idea there that sort of felt like underneath all of this excitement and newsworthiness is the soul of a woman. And that didn’t need a lot of covering up." Caitlyn, Jessica mentions, also already "has a pretty good idea of what makes her feel good, and those are classic silhouettes."

In a new video from the magazine, Caitlyn elaborates on her aesthetic and explains that it was paramount to her that, when she came out, that she look "the part, very feminine."

Caitlyn also discusses the pioneers who came before her and what—and who—she hopes to inspire for the future. Watch the clip above, and be sure to check out the full interview with Jessica Diehl on Vanity Fair.
