Venus and Serena Williams may play when it comes to the courts, but not when dressing to impress — which is exactly what they did at their friends Brooklyn Beckham and Nicola Peltz’s wedding. Serena posted a picture of her and her sister posing in their designer mini dresses and open-toed straps.

Serena wore a charcoal-colored Balmain long-sleeved mini dress that flaunts her long-stemmed legs, which she paired with sparkly strapped heels and sported a honey blonde ombré bob. Venus wore a red fringed mini dress, showing off her gorgeous gams as well, and paired her outfit with ankle strap heels and a gold clutch. The drop earrings she wore complimented her long and high ponytail.

Serena’s Instagram post included multiple slides of her posing with social media influencer Amber Ridinger, Amber and her mom, Loren Ridinger, and a photo from Vogue of Nicola at her wedding ceremony.

The post’s caption reads, “My sister @venuswilliams and close friend’s wedding weekend. Congrats, @nicolaannepeltz and @brooklynpeltzbeckham, on finding true love.”

Amber’s most recent post was similar to Serena’s, but the one before that one is a selfie with her, her mother, Serena, and Eva Longoria.

According to Vogue, the wedding took place at Nicola’s family’s oceanfront home in Palm Beach, FL. And from the way Vogue described the wedding, this wasn’t the typical wedding where everyone dances to the “Cha Cha Slide,” it was a very lavish event with black ties, string and jazz quartets, and exquisite designer dresses. Nicola walked down the aisle to a live rendition of “Songbird,” played by a string orchestra, holding her father’s arm. Valentino made Nicola’s gown, and the bridesmaids wore dresses made by Joel Diaz.
