Caitlyn Jenner Discovers the Need for Sports Bras in New 'I Am Cait' Preview

Caitlyn Jenner is taking it all in!
In a preview for her E! reality show I Am Cait, the 65-year-old former Olympian is seen out and about with her friends and family. "I have a lot to learn," she admits.
While much of the promo shows the fun Jenner is having in her new life, she's also pretty open about the downfalls that come with femininity.
Jenner hits the court for a game of tennis in a darling all-white ensemble. But after playing a few rounds, she exclaims, "Now I know why girls need a sports bra."
Her step-daughter Kim Kardashian also reveals to the reality star that her ex-wife, Kris Jenner, has the same little black dress as she does. Upon learning this, Jenner just shrugs a bit and laughs.
The one-minute preview shows lots of scenes with Jenner laughing with friends, and even offering up beauty tips. "All of a sudden, I am the authority on hair and makeup," she exclaims.

A more emotional scene occurs when Jenner explains her journey to her 89-year-old mother, Esther Jenner.
