The brand new trailer for the documentary gives us further glimpses inside Caitlyn's glamorous world – including her wardrobe – and explains why she chose to tell her story on screen.
In one scene, we see 17-year-old Kylie cuddling up to Caitlyn in a hug.
Caitlyn reveals via voiceover: "Why did I decide to do a series? I am telling my story. People don't understand what it's like to look in the mirror and nothing seems right. Or to put on clothes you don't identify with. This is about getting to be who you really are."
The trailer can be viewed here.
Caitlyn adds of what we can expect from the show: "We're going to talk about everything. We're going to do a lot of fun things for the first time. We're going to go shopping for the first time. Maybe even some boy stuff, like ride a motorcycle - because girls do that, too!"
I Am Cait begins Sunday 2,August at 9pm on E!
