Serena Williams Swapped Her Stilettos for Sneakers at the Royal Wedding Reception Serena Williams was the picture of elegance at Prince Harry and Meghan Markles royal wedding ceremony at St. Georges Chapel in Windsor Castle, wearing a blush Versace dress and matching sky-high heels. But when it came time for the reception, the tennis pro kept it real by channeling her inner athlete. By nightfall, Williams, who documented Meghan and Harrys big day on her Instagram stories, slipped out of her Versace ensemble in favor of a floral, floor-length gown by Valentino, and, her dress wasnt the only swap. The mom of one exchanged her stilettos for a comfy pair of sneakers. Little known fact: I often wear sneakers under my evening gown, she wrote next to a video of her and her husband, Alexis Ohanian, walking to a bus that whisked them to the Frogmore House dinner reception hosted by Prince Charles.
