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.

“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!

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.

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.”

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.”

“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.”
