"It's so important to believe in yourself" - Serena imparts wisdom during appearance on Project Runway finale

The 23-time Grand Slam champion often designs her on-court outfits, and in fact has her own line of designer apparel, "Aneres" - which is her first name spelled backwards. In addition, she also launched a signature collection of handbags and jewelry in 2009.

It comes as no surprise that the 2020 Auckland champion is well-connected in the world of fashion. Williams was recently a guest judge on the season finale of Bravo's Project Runway, where she passed on her knowledge to the four finalists.

The finalists consisted of designers Victoria Cocieru, Sergio Guadarrama, Geoffrey Mac and Nancy Volpe-Beringer. With Mac being the eventual winner, Williams was full of praise for the Chicago native, who admitted to having self-doubt during the shooting of the show.

"It's so important to believe in yourself," she told him. "In my job, I look different, and that kind of put me on this path of being different.

You have a lot to say and to design, and you should just be yourself."

Williams also recognized the efforts of runner-up Volpe-Beringer, which integrated sustainability into fashion.

“We have to somehow figure out how to live on this planet and not destroy it, so this really speaks to me personally," Williams said of the collection, and the efforts for sustainability as a whole.

"It has to be incorporated into design as well because fashion is a really big part of a lot of bad things that are happening and it’s just the honest truth." Williams added. "It’s about how do you create those collections that are more sustainable and takes less pressure from what we do.”

Her appearance on the reality show adds to her growing fashion accomplishments this year. In February, she presented the spring 2020 collection for her S by Serena clothing line at New York Fashion Week.
