Brianna Guagliardo, girlfriend of tennis player Luciano Darderi, posted a ballet-inspired outfit on social media in the lead-up to Darderi's match against Alexander Zverev at the U.S. Open.

Guagliardo, who teaches ballet in Argentina, shared a photo on Instagram wearing a pale yellow crop top over a brown polka-dot bra top with matching high-waisted shorts. The post was captioned, “all smiles💛🌻🌙🌼.”

It is unclear if Guagliardo is attending the U.S. Open match in person, though she has been present at Darderi's significant tournaments in the past. Darderi is scheduled to play Zverev on Monday in the Round of 16.

Darderi, the tournament's 21st seed, has advanced through the tournament having lost only two sets in his previous three rounds. Zverev, the top seed in the tournament, is facing adversity as a result of Jannik Sinner's withdrawal due to injury. This match marks a new stage for both players in the tournament.
