Caitlyn Jenner Explains Why Do Docu-Series in New 'I Am Cait' Promo

— -- A new promo for "I Am Cait" is here and it shows Caitlyn Jenner explaining the show and how she hopes the 8-part docu-series will inspire others.

"Why did I decide to do a series?" Jenner says in the clip. "I am telling my story."

The former Olympian and reality star, 65, continues: "People don't understand looking into the mirror and nothing seems right. Putting on clothes that you just don't identify with. This is about getting to be who you really are."

Caitlyn made her debut at the beginning of the month on the cover of Vanity Fair and the new clip shows her hanging with friends and her daughters.

"We are going to do a lot of fun things for the first time," she says. "Go shopping for the first time. Maybe boy's stuff like ride a motorcycle, because girls do that too! It's going to be quit a journey, we are going to do some good."

"I Am Cait" premieres July 26 on E!
