Caitlyn, 65, was known as Bruce Jenner before undergoing a gender transition, reported People magazine.
"People don't understand looking into the mirror and nothing seems right, putting on clothes that you just don't identify with," Caitlyn said in the promo.
"This is about getting to be who you really are. 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 some boy stuff like ride a motorcycle - because girls do that, too! It's going to be quite a journey. We're going to do so good," she added.
