The 2025 US Open has kicked off at the Billie Jean King National Tennis Center in New York City and so far, both the tennis players themselves and A-list attendees have shown off some stunning looks.

Sunday marked the official start of the tournament, but qualifying round games have been going on since last week.

Of course, top players like Aryna Sabalenka, Coco Gauff, Jessica Pegula, Jannik Sinner, Carlos Alcaraz and Taylor Fritz will all be playing in the high-pressure event. 

Many celebrities arrived at The Us Open on Sunday to see the opening matches, and they were all dressed up in their best end-of-summer outfits.

Hilaria Baldwin watched on with her husband, Alec Baldwin, wearing a stunning, light blue silk dress by the brand Saloni, complete with a deep v-neck and puff sleeves for the occasion.

The dress, which is currently on sale at The Outnet for $209 from its original $700,  also featured tiny yellow embroidered flowers at the bust and a slit in the front. 

And blue seemed to be the color of the weekend, as former tennis pro Serena Williams made a surprise appearance to induct fellow player Maria Sharapova into the Tennis Hall of Fame.

Williams wore a beautiful, light blue knit mini dress by designer Balmain, which was decorated with large gold buttons at the bust.

The adorable summer dress retails for $3,090 at major retailers like Neiman Marcus and Saks Fifth Avenue.

The mom-of-two paired the dress with a pair of sold-out metallic rainbow ombre heels by Christian Louboutin, whose shoes usually retail for over $1,000.

Although her exact pair by the famed shoe designer is no longer available, Christian Louboutin still has a handful of metallic shoes in pinks and purples left over from the season.

Former athletic gymnast Livvy Dunne also sported a fun ensemble for the day, as she wore a strapless, brown-and-white polka dot dress with a matching scarf.

It's unclear exactly where Dunne bought her dress, but a similar look is available for $50 at Princess Polly.  

Other celebrities still wanted to wear their summer whites, like CBS News journalist Gayle King.

King stunned in a form-fitting, knit white dress that hit her at the knee by Self-Portrait.

The casual dress, which retails for $555 on their website, also features a sailor-style collar with navy blue detailing.

She paired the look with bright fuchsia heels and a bag in the same color that was in the shape of a bow tie.

Actress Angela Kinsey also sported a fun bag by Kate Spade that was in the shape of a green tennis ball.

The bag is no longer available for purchase, but there are many dupes available online, including on Amazon.

Though, of course, the tennis players in the US Open themselves were serving looks on the court, like Jessica Pegula.

Pegula looked seriously stylish as she played in a $200 white tennis dress with gray and orange detailing last week.

Even if you're not a tennis player like Pegula, you can still buy the dress at retailers like Shopbop.

Aryna Sabalenka also wore one of Nike's newest tennis dresses on Sunday, which is available from Nike for $130.

The white dress featured black leather straps, and cutouts at the waist and back, taking tennis fashion to the next level.
