Serena Williams married Reddit co-founder Alexis Ohanian in November 2017 in an intimate, private ceremony. At the themed wedding, Williams captivated her guests with not just one but three outfits, including the most expensive wedding dress ever.

Williams emerged in an emotional strapless, belted princess gown with a cape, designed by Sarah Burton for Alexander McQueen. Burton also designed Kate Middleton’s wedding dress when she married Prince William to become the Duchess of Cambridge.

The 23-time Grand Slam champion carried a bouquet of white roses and dazzled with jewelry by XIV Karats, a Beverly Hills-based company known for sourcing natural, ϲоnflιϲt-free earth-mined diamonds and gemstones. Altogether, the ensemble cost approximately $3.5 million, making it the priciest celebrity wedding dress of all time.

In an Instagram post showcasing her dress, Williams revealed that she chose the designer on the recommendation of her friend Anna Wintour, Vogue’s Editor-in-Chief. The former World No. 1 desired to wear a dress with a cape, and Wintour mentioned that Burton was the only designer who could fulfill Williams’ requests.

“For the first dress, when Anna Wintour asked me what I wantеd to wear I said ‘a cape, I just want to wear a cape,’” Williams wrote on Instagram. “She said, ‘well Sarah Burton with @alexandermcqueen is the one for you.’” Serena Williams also expressed gratitude to Wintour and Burton for making her dreams come true, stating that she “felt like a princess and superwoman” in the dress. “Thanks Anna. Thanks Sarah. I felt like a princess and superwoman all at once,” Serena said.
