As the world's greatest tennis players descend once more on Melbourne's Rod Laver Arena for the scorching competition that is the Australian Open, several of the leading figures are looking just as sharp off court as they are in active wear.
We take a look at the style leaders making their mark, from world champions to an Australian hero's swansong.
Novak Djokovic, Serbia
Crown king of the world and scooper of last year's Australian Open title, Serbian player Novak Djokovic has a distinct look all of his own off court, successfully matching casual polo shirts, collar up rakishly, with smart suits. At 6 foot 2 with a powerful but trim build, he looks good in bright coloured Uniqlo tops on court and even better in pinstripes striding the catwalk alongside Naomi Campbell at the Fashion For Relief show during the 2011 Cannes Film Festival.
Feliciano Lopez, Spain
Spain's Feliciano Lopez cuts a dashing figure with his dark trimmed beard, flowing locks and piercing eyes. Currently ranked 19th in the world, the 34-year-old married partner Alba Carrillo last year in his hometown of Toledo sporting a slick suit, navy tie and pin stripe shirt combo. Fellow players Fernando Verdasco, Marcel Granollers, David Ferrer, Albert Costa and Alex Corretja formed an arch across the aisle with their tennis racquets.
Fabio Fognini, Italy
Currently ranked 21st, handsome Italian Fabio Fognini further upset an already troubling year for tennis hero Rafael Nadal when he trounced the Spaniard at the 2015 US Open, before bombing out thanks to Lopez. Fogini's a smooth mover off court too, sporting Armani amongst the world's most stylish while attending Milan's Fashion Week last year with fiancé and fellow tennis ace, the now retired Flavia Pennetta.
Grigor Dimitrov, Bulgaria
28th globally and top ranking in his home country, Bulgarian player Grigor Dimitrov resides in Monaco's elite enclave of Monte Carlo, where the fashionable look of its super-rich residents has rubbed off. A former partner of Russian tennis great Maria Sharapova and US star Serena Williams, he's now linked to Nicole Scherzinger. Looking pretty dapper in Ralph Lauren for a 2014 American Vogue shoot, but was far more casual when visiting the cute critters at Sydney's Taronga Zoo this week.
Stan Wawrinka, Switzerland
Swiss star Stan Wawrinka is currently ranked 4th in the world and just secured his third win in a row at the ATP Chennai Open, wowing Indian fans with his win against Croatian Borna Coric. Stripping down to his birthday suit for last year's ESPN magazine's Body Issue, Wawrinka gets a fair amount of stick for the length of his boldly plaid shorts on court, but we think he looked pretty spiffy in Armani at the 2014 Milan Fashion Week.
Lleyton Hewitt, Australia
The youngest ever player to become the world number one, Adelaide-born Lleyton Hewitt will take his final bow at this year's Australian Open in what's sure to be an emotional scene for local fans. Attending the Swisse marquee at last year's Melbourne Cup with wife Bec, he looked stylish in a steely blue three-piece suit, checked shirt and flock-patterned tie.
Sloane Stephens, USA
Five years into her professional tennis-playing career, 22-year-old American Sloane Stephens, currently ranked 26th, is making her mark on the game. Winning the ASB Classic tennis tournament in Auckland, she pulled out of her top seeded position in Hobart to conserve her game for Melbourne's Australian Open. A sterling performer on the court wearing Under Armour, the Alexander McQueen fan also looks fabulous in Donna Karan and Stella McCartney in a 2013 shoot for W Magazine.
Sania Mirza, India
India's Sania Mirza may have retired from the singles game, but far from putting her feet up, the right-handed star is currently ranked number one in women's doubles, winning the Brisbane International last week with partner Martina Hingis. Responding to a backlash over her fashion sense on court, the savvy Mirza noted, "As long as I'm winning, people shouldn't care whether my skirt is six inches long or six feet long." Reserving her right to dress as she pleases, Sania dazzled on the catwalk at last year's India International Jewellery Week.
Maria Sharapova, Russia
Ranked 5th in the world in women's singles, Russian megastar Maria Sharapova may have had to pull out of the Brisbane International with a forearm injury sustained during practice, but she's aiming to be back on court for the Open. A global icon celebrated for her sporting prowess, she also attracts the attention of the fashion crowd, seated front row at the Valentino Spring/Summer 2016 show at Paris Fashion Week, where she also attended Chanel.
Ana Ivanovic, Serbia
28-year-old Serbian star Ana Ivanovic trained in the midst of NATO air strikes during the Kosovo War, proving her mettle, which saw her achieve number one ranking after the 2008 French Open at only 21. Currently ranked 22nd, she's a popular star on and off the court, has graced the pages of Vogue, Harper's Bazaar and Vanity Fair and has been known to hang out with Anna Wintour and designer Oscar de la Renta at New York Fashion Week.
Victoria Azarenka, Belarus
Statuesque Belarusian player Victoria Azarenka is another former number one and a two-time Australian Open winner. After a tough 2015, the 26-year-old championed this year's Brisbane International. Rather amusingly, she interrupted her own press conference at last year's Australian Open to quiz one journalist on what he thought of her on-court outfit – the verdict: he liked it, but too much yellow/long sleeves. Clearly keen on looking cool, Azarenka has graced catwalks too.
Serena Williams, USA
The world number one-ranking Serena Williams is a dead set legend on or off the court, inspiring millions. The 34-year-old has 21 Grand Slams to her name, but she's already looking to the future with a career in fashion design for label HSN. Speaking about the HSN look, Williams told Vogue, "I want [my customers] to feel empowered. I want them to feel beautiful. The collection works on every size person. You should [be able] to look good and feel good and love who you are and, at the same time, be stylish."
