Caitlyn Jenner is seen trying on a wedding dress and meeting Democratic presidential candidate Hillary Rodham Clinton in a just released trailer for the second season of I Am Cait.

The reality show that follows Jenner and her friends returns for its sophomore season on Sunday, March 6 on E!

“You have to show you're fighting for everyone,” author-activist Jenny Boylan is seen telling Jenner in the trailer. “Not just the pretty ones.”

“I've made mistakes along the way,” an emotional Jenner says. “I have to evolve as a person. There's just too much at stake to get it wrong.”
