Australian Open fashion review: Bright colors, new labels shine at season's first Grand Slam

The year’s first Grand Slam is in the books, with Jannik Sinner and Madison Keys crowned Australian Open champions—and it’s nearly a podium sweep for their shared apparel sponsor Nike, who outfitted three of the four singles finalists in Melbourne.

But it wasn’t just the big names that waves Down Under: We saw luxury men’s clothing brand Psycho Bunny officially make its Grand Slam debut, an Aussie qualifier’s online shopping spree go viral, and another Russian tennis player launch their own fashion project.

From Naomi Osaka’s sunflower powered custom Nike kit to Frances Tiafoe’s debut in Lululemon, here are the outfits that turned heads in Melbourne Park:

Aryna Sabalenka, Madison Keys — Nike

With the joy of Melbourne’s beaches as its inspiration, Nike unveiled a bright and colorful 2025 Melbourne Collection for players like Aryna Sabalenka, Madison Keys, Paula Badosa, Mirra Andreeva and more. The collection was highlighted by the Spring Melbourne dress, which comes in ‘mineral teal’ and yellow and features a contrasting cami layered on top.

While the added overlay received mixed reviews on social media, Nike had the last laugh as the women’s final became an all-Swoosh affair as Keys faced Sabalenka for her first Grand Slam title.

Carlos Alcaraz, Jannik Sinner — Nike

A slightly muted version of the same blues and yellow were spotted on Nike’s ATP representatives in a variety of mix-and-match separates. Jannik Sinner charged to his third Grand Slam trophy in a ‘luminous green’ Spring Advantage polo, while Carlos Alcaraz opted for a cool teal Melbourne Advantage Sleeveless top.

Naomi Osaka — Nike

Naomi Osaka channeled the Australian summer sun in a floral-inspired custom Nike kit that was all the talk of the first week in Melbourne. Osaka’s muted black and grey top and skirt were elevated with a bright pop of orange on her GP Challenge 1 Osaka shoes—which feature sunflower details. The two-time AO champ completed the look with sunflower accessories, from hair clips to earrings.

“The Australian Open's the Happy Slam, so I thought it was really fitting for it to have a sunny theme,” Osaka said.

Frances Tiafoe, Leylah Fernandez — Lululemon

Advantage, Lululemon. The Canadian sportswear announced Frances Tiafoe as its latest ambassador in tennis ahead of the Australian Open. The American, who joins Leylah Fernandez on the Lululemon roster, took the court in Melbourne in a “passionate” pink ensemble.

“I’m really excited to wear Lululemon on the court,” Tiafoe said in an interview with Forbes. “I got to give a lot of input into my look which feels very me and shows off my style. Working with a brand that’s newer in the tennis world is really cool because they care about both performance and style.”

Zhang Zhizhen, Andrey Rublev — K-Swiss

It was all about pink at this year’s AO, and K-Swiss kept the trend going with ambassadors like Zheng Zhizhen and Andrey Rublev.

The Russian knows a good tennis kit—check out his fashion brand Rublo if you need any proof—and he hit the mark once again in Melbourne with a bright pink and navy blue outfit complete with white and pink shoes.

Marta Kostyuk — Wilson

Ukraine's Marta Kostyuk has been a Style Points regular since becoming Wilson’s first 360 athlete back in 2023. Some of her Grand Slam kits even landed her on the pages of Vogue—like last year’s Wimbledon dress, which was inspired by her own Wilson-designed wedding dress.

In Melbourne, Kostyuk turned heads in Wilson’s Tour Perforated Dress in “Infrared”, which blends light weight and high performance with a built-in bra and racerback straps.

Coco Gauff — New Balance

Coco Gauff rocked one of the most eye-catching outfits of the fortnight in a superhero-inspired bodysuit and skirt by New Balance. The set came in cool green for daytime and neon yellow for night matches, and the American completed the look with her signature Coco CG2 shoes.

“I’m a huge Marvel fan, and a lot of the female superheroes have cool cut-outs on their outfits. That’s what I wanted to do,” Gauff said in an on-court interview.

“It’s actually kind of a pain to get into because it is a bodysuit, guys!” she revealed. “I have to put the bottom part on first and pull it over my head. It’s kind of a struggle, and if you can’t hold your bladder, it’s also not a good idea… A couple times I’ve had to ask the referee to help unzip me to use the bathroom!

“You have to sacrifice for fashion!”

Novak Djokovic — Lacoste

It’s tough to really rock an all-blue kit in Melbourne, where the bright colors of Rod Laver Arena make it look like players are competing in a swimming pool. But when you’re the 10-time champion Novak Djokovic, it’s not hard to stand out from the pack.

The former world No. 1 wore a polo from his Lacoste x Novak Djokovic collection that featured his logo on the left sleeve and a clay-court inspired white cross along the front. He completed the look with blue Asics Court FF Novak shoes, and his familiar Head Speed Legend racquet in an exclusive all-black colorway.

Elina Svitolina — Adidas

Elina Svitolina stood out in a head-to-toe Semi Lucid Red look featuring a cap-sleeve dress with cutouts along the shoulders. The No. 28 seed completed the look with accessories by SOLO for Diamonds, a Ukrainian jewelry company that specializes in lab-grown diamonds.

Ben Shelton, Iga Swiatek — On

There's an old saying: If it’s not broken, don’t fix it. On seems to be keeping to this motto for its tennis apparel, with Iga Swiatek, Ben Shelton and Joao Fonseca hitting the courts in Melbourne wearing the familiar gradient color scheme and minimalist silhouettes that have become its staples.

This year’s collection features functional mix-and-match separates with an ombre swirl that goes from pink to orange to yellow—a nod to Melbourne’s sunny summer weather.

Alexei Popyrin — Psycho Bunny

One of the fashion highlights of this AO was seeing the amount of new names hitting the courts in Melbourne. Men’s streetwear brand Psycho Bunny made its Grand Slam debut after announcing home hope Alexei Popyrin as its first brand ambassador in tennis at the start of the year.

“It’s impossible to escape Psycho Bunny. Their magnetic logo and energy made it a brand I always kept my eye on,” Popyrin said. “Wearing their high-quality fabrics on court was an eye-opener, but meeting the team really sealed the deal for me. Their passion and commitment to the sport inspired me, and after seeing their tournament takeover in Montreal, I knew I wanted to partner with them.”

Thanasi Kokkinakis — Cotton On

One of the standout looks from Week 1 came from Thanasi Kokkinakis, who unveiled the limited-edition “Kokkinakis Shorts” ahead of the tournament. Designed in collaboration with the player, the blue shorts with a “Spartan warrior” motif were a nod to his Greek heritage—and they quickly went viral in Australia after fans learned that it was made by local lifestyle retailer Cotton On.

“I’m very proud of my heritage and couldn’t be more grateful for the Greek community’s support,” he told Greek City Times. “They’ve always been there for me, and it feels special to give something back to them with these shorts.”

Destanee Aiava — Player's own thrifted pieces

Qualifier Destanee Aiava captivated Melbourne audiences during her run to the second round by wearing vintage tennis dresses once worn by Maria Sharapova, Ana Ivanovic and more. The 24-year-old, who does not currently have an apparel sponsor, found the pieces on sites like Ebay and Facebook during Black Friday last year.

“It was an impulsive buy,” the Aussie revealed. “I just wanted to find some old dresses that nobody was wearing anymore and some looks that I thought were iconic.

“I decided to wear a few this AO because I don't have a sponsor. Somehow it got picked up by everyone and now it's blown up, which has been pretty cool."

Anastasia Pavlyuchenkova — Player's own collection

Anastasia Pavlyuchenkova is the newest player in tennis’ fashion game. Previously outfitted by Lacoste, the Russian player had been without an apparel sponsor for about a year before unveiling her new kit—which she designed and created herself.

“This is a trial run, I already have a couple of sets of dresses and skirts with tops,” Pavlyuchenkova shared on Instagram.

“The dresses are quite revealing with open cuts in delicate colors. Lavender is one of my favorites, (and) I added some yellow since it's the beginning of the season in Australia. Australia is sunny, so yellow.

“There are elements of little bows because I think bows are feminine and trendy right now.”
