At Serena Williams' anticipated S by Serena fashion show, her daughter, Alexis Olympia Ohanian Jr., made an adorable surprise debut.

The Autumn/Winter 2019 runway show at Klarna with Style360 was full of amazing looks from the tennis star's "see now, buy now" collection. Daughter Olympia's presence made the show even more exciting.

Williams wore a black sheer top, snakeskin print skirt, and sneakers as she took a final wave holding her baby girl at the show's conclusion.

The looks from the show including a mix of designs -- from plaid prints to sequin textures on jumpsuits, dresses, outerwear, blouses and more.

"This collection is a celebration for those who break limits, boundaries, and tradition," said Williams in a statement.

She continued, "This is designed for people who turn fear into courage and doubt into confidence -- from indomitable mothers, daughters, and sisters to resilient business owners and entrepreneurs, young girls with crazy dreams, and women of color who show no fear in the face of adversity or challenge."

In addition to Olympia's surprise moment on the runway, Kim Kardashian West also made a surprise appearance at the show. Other all notable front-row faces present included basketball star Rick Fox, model Ashley Graham, and Vogue editor-in-chief Anna Wintour.
