On Wednesday morning at Spring Studios, Serena Williams put on her second-ever New York Fashion Week runway show. She displayed looks from her S by Serena line for her 2020 spring collection.

Caroline Wozniacki was on hand to support the 38-year-old, and so was Karlie Kloss and Andre Leon Talley. 

Serena also sat down with fashion icon Anna Wintour.

The Oscars came up in their conversation.

"I was so moved by what Renee [Zellweger] said," Serena said to Wintour. "First of all, I was shocked. I was like, wait, did I just hear that?"

Last year, Serena made her NYFW debut as a designer just after reaching the US Open final. She just had another successful show fresh off of helping the U.S. Fed Cup team qualify for the finals in Budapest. 

Serena isn't the only tennis player makes waves this week in New York. On Tuesday, Naomi Osaka made her first foray into the design world by unveiling some of her own creations at the ADEAM show.
