Work the runway! Caitlyn Jenner channels her supermodel daughter Kendall Jenner in a clip from the Aug. 23 episode of her E! docuseries, I Am Cait.

The Olympian's visit to designer Patricia Field's New York City boutique was captured by paparazzi back in June, weeks after Jenner's public introduction on the cover of Vanity Fair, and now you can see just what she was up to inside the shop: getting fashion advice from the legendary costume designer herself, of course.

"I think it's so important to catch her essence and then develop it in our way," Field tells the camera. "I try to get to understand her taste, her soul, her heart. She has to feel comfortable, otherwise the clothes are wearing her and we don't want that."

Is it working? "I can tell she's feeling it," the Sex and the City costume designer reveals.

It's easy to see that Jenner is loving her look as she exclaims, "I gotta get ready for Kendall's runway!"

After the visit, she reflects on how much the moment meant to her. "What an amazing experience, to meet and spend some time with Patricia," Jenner says. "Over the years, she has been very supportive and committed to making a difference. For the transgender community, that, to me, is, like, amazing."

I Am Cait airs Sundays at 8 p.m. ET on E!.
