Tennis fashion designers are busier than ever, as competition and demand keep growing, so it’s not easy to pick the Top 5 looks that marked the 2018 season.

Marija Zivlak of Women’s Tennis Blog has undertaken the tough task of selecting the best of the best, judging the outfits by their visual appeal, innovativeness, and wow effect.

Caroline Wozniacki finally crowned her career with a Grand Slam title at the 2018 Australian Open, wearing an outfit that was as extraordinary as her achievement. The Dane lifted the Daphne Akhurst Memorial Cup in the adidas Melbourne Jumpsuit, a laid-back 3-in-1 piece inspired by the relaxed Australian summer.

The super soft jumpsuit combines colors teal and yellow, reflecting Melbourne’s famous coastal city landscape. The casual silhouette makes this look perfect for the beach as much as the tennis courts.

The Climacool-equipped design incorporates a bra and built-in compression shorts. Enhancing performance and casual feel of the lightweight jumpsuit are honeycomb mesh and keyhole at back.

Serena Williams is always in the spotlight, both because of her unprecedented athleticism and because of her daring on-court fashion.

For her return to Grand Slam action after maternity leave, the American materialized her superhero powers in a black Nike catsuit at Roland Garros, a very atypical look for tennis tournaments.

Williams’ childbirth almost cost her her life and the catsuit helped her deal with blood clots. Nevertheless, from now on she’ll have to take a more conservative approach to her fashion - at least in Paris.

Andrea Petkovic's adidas Roland Garros Dress gives a fresh twist to the retro aesthetics. Tricolor trims, V-neck and a pleated hem are a nod to Parisian style and classic tennis looks across the decades.

Slim fit, comfortable and lightweight Climachill fabric and dominant coral tone that blends with the French Open clay make this dress a perfect mix of traditional sportiness and elegance.

Another beautiful modern outfit with a retro vibe was worn by Karolina Pliskova at the Porsche Tennis Grand Prix.

The Czech won the title in the Fila Spring Pia Sleeveless Polo and Fila Saffira Skirt. The sleeveless polo features ribbed collar, pinstripes, contrast armholes and snap button placket, while the all-around pleated skirt has red and white striped elastic waistband with a nice “F” logo touch.

Nike swept Roland Garros with a new approach to tennis fashion -- they opted for simple cuts and picked one perfect color (neo turquoise) to contrast the tournament’s surface, bringing all the attention to textural details, i.e. engineered knit.

The tridimensional outfit in which Simona Halep won her first Grand Slam title consists of the Nike Summer Zonal Cool Slam Tank and the Nike Summer Zonal Cool Smash Skirt.
