Caitlyn Jenner picks out KRIS JENNER’S DRESS in new I Am Cait trailer!

Caitlyn Jenner can be seen taking fashion advice from stepdaughter Kim Kardashian in the latest teaser trailer from her new E! docu-series, I Am Cait – so expect to see her striding around in some serious trench coats and peep-toe boots very soon.

The newest clip shows Caitlyn and Kim in one of their wardrobe rooms as Cait holds up a black dress and Kim has to tell her, "Mom has that". Awkward!

We also see Caitlyn having an emotional talk with her daughter, 17-year-old Kylie Jenner, telling her she still wants Ky to "be proud of her daddy".

Then she's filmed having a chat with a group of youths and telling them: "We're all beautiful!"

N'aww.

Since revealing her new identity at the beginning of June, Caitlyn has been making waves and working with the transgender community to help other people be who they are.

She's also started blogging, with her first post published last night.

In it, she thanks everyone for their "overwhelmingly positive" support and says she's "eternally grateful" for all the messages, letters and gifts she's been sent.

"Up until now, I have totally isolated myself from the transgender community so I have a lot of catching up to do," she goes on.

"I feel such a responsibility to this courageous group to try to get it right and tell all sides of the story. To me, that’s always the biggest question: am I doing it right?"

Caitlyn also highlights the many issues trans people face, including bullying, abuse and the prevalence of transwomen in the sex industry, and says she'll be talking more about them on her blog.

She finishes: "Let's live our true selves and make a positive difference while doing it."

I Am Cait premieres on Sunday 2 August at 9pm on E!.
