Serena Williams tied the knot with Reddit co-founder Alexis Ohanian in November 2017 in an intimate, private ceremony. At the whimsically themed wedding, Williams dazzled her guests with not one, but three outfits, including the most extravagant wedding gown ever.

For her entrance, Williams wore an emotionally charged strapless gown with a belted princess silhouette and a dramatic cape, designed by Sarah Burton for Alexander McQueen.

Burton, renowned for designing Kate Middleton’s wedding dress, created a stunning ensemble for the 23-time Grand Slam champion. Williams accessorized with a bouquet of white roses and jewelry from XIV Karats, a Beverly Hills-based company known for sourcing natural, conflict-free diamonds and gemstones.

The entire ensemble came with a hefty price tag of around $3.5 million, making it the most expensive 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. Williams expressed her desire to wear a dress with a cape, and Wintour suggested that Burton was the perfect designer to fulfill her vision.

“For the first dress, when Anna Wintour asked me what I wanted to wear I said ‘a cape, I just want to wear a cape,'” Williams shared on Instagram. “She said, ‘well Sarah Burton with @alexandermcqueen is the one for you.'”

Serena Williams also expressed her gratitude to Wintour and Burton for making her dreams a reality, 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 expressed her gratitude.
