From big bows to bold prints, who wore on-court fashion best in the 2024 tennis season?

While fashion had its moment off the court in the 2024 season with a renewed and revitalized "tenniscore" trend, that didn't mean that on-court looks were lacking across the year.

But from big bows to bold prints, who truly wore it best? Without further ado, here are Baseline's top on-court 'fits of the last year.

Naomi Osaka's Harajuku-inspired US Open 'fit (Nike)

Naomi Osaka's return from maternity leave saw the former world No. 1's on-court performance, and her in-press and online candor, as she sought to find her vintage form. Her style game, though, was like she never left. Osaka was disappointed that the custom look Nike created for her Grand Slam return only got one match worth of action, as she lost in the first round to Caroline Garcia, but gave fans another look at the high-neck number and its iridescent snake-skin patterned "scales" by wearing it again in Doha. She debuted asymmetrical red-and-blue Nike shoes, inspired by her homeland, in the spring, while her elaborate multi-ruffled white Wimbledon dress even left the internet divided.

But the four-time Grand Slam champion saved her best look for the year's last Grand Slam, debuting a dramatic Harajuku-inspired 'fit at the tournament she's won twice previously. It was designed in collaboration with Nike and Japanese designer Yoon Ahn, founder of the Tokyo label Ambush.

After beating Jelena Ostapenko for the first Top 10 win of her comeback in the Tinkerbell-green version, Osaka showcased an alternate colorway, black and white, in her second-round loss to Karolina Muchova in an Arthur Ashe Stadium night session.

Though the outfit wasn't in New York for a long time, it was there for a good time, with Osaka saying that she pushed aside thoughts of the whole ensemble being "too much" and crediting Ahn for embracing her vision.

“I definitely love to be involved in everything I do, whether it's fashion or anything else," she said. “But I feel like being able to be a part of my tennis outfits gives me, I would say, a different strength.

“I think for me, when I put on the outfit it's almost like a super suit, so I try to channel that."

Ajla Tomljanovic goes bold on the Parisian clay (Original Penguin)

As the first tennis player to sign with Perry Ellis subsidary Original Penguin in 2022, Ajla Tomljanovic has been a foundational model for the heritage athleisure brand to tap into new markets and audiences.

While Tomljanovic's 2024 season was a rebuilding one after she missed much of 2023 following knee surgery, she made a statement sartorially with an eye-catching, blue and white two-piece during a short stay at Roland Garros.

Though the 31-year-old lost in the first round of singles and doubles in Paris, her long-sleeved patterned crop top and matching skirt were accented with pops of pink, and she accesorized with a blue Penguin visor and Wilson’s Rush Pro shoes in peachy pink.

Tres Magnifique!

Coco Gauff and Emma Navarro: Regal in NYC ruffles (New Balance and Fila)

Coco Gauff and Emma Navarro created the burgeoning beginnings of a rivalry in 2024, and when they met on home soil in New York, they were dressed to impress. While there was a lot different about Gauff and Navarro's paths to the WTA's year-end Top 10, their fashion choices, from two competing brands in New Balance and Fila, respectively, were strikingly similar at the US Open, where Navarro ended Gauff's title defense in the fourth round.

In one corner was the 20-year-old Gauff, wearing a cornflower blue dress that hinted at separates, thanks to strategic cutouts at the midriff and lower back, while rocking a new "Coco CG2" signaure shoes in the Power and Grace colorway that debuted shortly before the tournament. She completed the look with a glittering Olympic tribute: a necklace of the Olympic rings, gifted to her by her and Navarro's Team USA teammate, Desirae Krawczyk.

In the other, the 23-year-old Navarro, who showcased Fila's Casa collection, which, according to the brand, "merged\] classic aesthetics with modern flair, refreshing iconic tennis looks for the contemporary player." Her beige-hued, cropped sleeveless polo shirt was paired with a pleated skirt, and cut a classy figure as she danced around the Open's biggest stage ... [all the way to the semifinals.

"Name brand" kits: Andrey Rublev and Donna Vekic have a moment

While top players have long had an input in how major tennis manufacturers clothe them, 2024 saw not one, but two big names take that relationship even further: Andrey Rublev and Donna Vekic looked on-point throughout the season wearing their own "name-brand" apparel.

In 2023, Rublev, once a client of Nike, officially launched his own clothing line "Rublo" that he'd been teasing for nearly a year, from which 100% of the proceeds will go towards children in need. Throughout 2024, the line evolved, as the world No. 8 showcased various desgins from the fledgling collection, and in August, he inked a deal with K-Swiss shoes with the promise of an upcoming collaboration.

Vekic, also a Nike alumna, joined Rublev in making the jump into fashion in 2023, partnering with Italian brand Uomo Sport to launch womenswear line "Donnasport," a fitting pair as "donna" means "woman" in Italian.

“This is a new chapter of my life, and it’s something I was missing with Nike, to be able to put my input into the design,” Vekic, who had worn Nike since her junior days, said at the time.

Clad in the high-end, retro-inspired designs, the Croatian had a banner second half of 2024, putting her in the year-end Top 20 for the first time, as she reached the semifinals of Wimbledon and won the silver medal at the Paris Olympics in a first for a Croatian woman in tennis.

At the Games, Vekic upset Coco Gauff and later saved a match point to beat Marta Kostyuk, and she did it in delicate, ballerina-inspired crimson-and-white separates that popped on the red clay.

Casper Ruud course-corrects at Olympics to Norwegian tri-color (Yonex)

Casper Ruud might've fallen short of the podium at his first Olympics, losing to Felix Auger-Aliassime in the quarterfinals, but he did his country proud on the fashion front ... well, eventually, anyway.

Ruud's Yonex-issued Olympic kit underwent a metamorphosis between his first-round win over Taro Daniel, and his second over Andrea Vavassori. For his Olympic debut, Ruud donned a near-completely red kit with white accents, leaving not only fans, but the Norwegian himself wondering why he looked so ... well, Danish.

The outfit even made waves in the media in Ruud's homeland, with TV presenter Marianne Jemtegård as a “total miss." But it also left Holger Rune, from the aforementioned neighboring nation, amused.

“People might think I play anyway,” joked the former world No. 4, who was forced out of the Games with a wrist injury.

Yonex quickly whipped up something more, ahem, Norwegian, and the blue color blocks occupied a place of pride close to Ruud's heart as he battled on for the rest of the tournament.

Anything Marta Kostyuk wore (Wilson)

Since debuting as Wilson's first head-to-toe athlete in 2023, Kostyuk has consistently raised the bar for on-court 'fits, working in tandem with the brand's head of design, Joelle Michaeloff, to create head-turning custom looks.

This year proved no different, with the Ukrainian routinely landing on best-dressed lists for her collaboration with the manufacturer. There was the pleated, forest-green number that boldly jumped out against the backdrop of the famed *terre* battueof Roland Garros; the tennis ball-yellow US Open dress that radiated in the Flushing Meadows sunshine; and, of course, the one-of-a-kind Wimbledon two-piece that was inspired by her wedding dress (also designed by Wilson) that she wore her 2023 off-season nuptials

The last one was so good, that Wilson even named it after Kostyuk.

Kostyuk's willingness to embrace style, on and off the court, is part of an on-and-off-court maturation, she exclusively told Baseline last summer.

“The most interesting part (of working with a stylist) was just to hear a professional opinion on how you look, like, what's your body type?" she said. "Because I think you judge yourself more strictly and differently in a way… As a person, you cannot really look at yourself from the outside and see how people see you.

“It's a personal preference, obviously. But it really helped me change the way I look at myself.”
