The 65-year-old, formerly known as Bruce, wowed in a floor-length navy gown with an intricate lace design on the back.
Her new photo shoot comes after the latest trailer for Caitlyn's new E! reality show was released.
In the clip, an emotional Caitlyn sobs as she insists she wants her children 'to be proud of their daddy'.
But it's not long before she and step-daughter Kim Kardashian, 34, are picking out dresses together.
It looks like Caitlyn picked up some style tips from ex-wife Kris Jenner in their 25 years of marriage.
As she shows off a black dress, Kim tells Caitlyn: "Mom has that!"
Brave Caitlyn recently opened up about why she is making her journey so public.
Writing in her new blog, she said: "You wouldn’t believe the types of ordeals these people have had, how they have had to literally fight for their own survival.
"Many trans teens are bullied and abused in high school. It’s just horrendous."
