Serena Williams Twins (& Twirls) with Daughter Olympia in New Instagram Video

When Serena Williams goes shopping, she must buy everything as a set of two.

The tennis pro and her daughter, Olympia, were seen twinning yet again in Williams's latest Instagram post. The slideshow included a video where Williams and Olympia twirled in a pair of burnt orange mini dresses with gathered skirts on the bottom. The pair also donned matching orange and blue Nike sneakers.

While the mom and daughter duo have their outfits down pat, they must have also been practicing their poses together, because in the two photos following the video, they each have their left leg bent and turned as they simultaneously look over their shoulders.

Although Williams didn't tag the label that designed their dresses, we're dying to know so that we can match with the family, too.

The official account for Williams's clothing line, S by Serena, commented on the post and said, “Omg here for this twinning moment.” Meanwhile, other users loved the slideshow, like one person who said, “OMG stahhhp with the cuteness.” Another added, “YESS! THE CUTEST MOM AND DAUGHTER DUO!”

Williams and Olympia have really been on a matching kick lately. When the pair attended the premiere of King Richard earlier this month (along with Williams's husband and Olympia's dad, Alexis Ohanian), they were seen wearing black bodysuits from London-based designer David Koma. The one-legged, bedazzled ensembles were paired with a complementing boot and opera gloves. But Williams and Olympia made sure to add their own personal touches with individual accessories.
