Nike Tennis has unveiled the looks its top athletes -- including Roger Federer, Juan Martín del Potro, Serena Williams, Maria Sharapova, Vika Azarenka and Li Na -- will wear on the courts of Melbourne this month. Nike Dri-FIT fabric will play a key role in combating the warm temperatures of an Australian summer.

Roger Federer

Federer will wear the Premier RF Polo, which features Dri-FIT UV fabric and bonded seams to maximize breathability and protect from the sun's rays. His shorts are made from Dri-FIT herringbone twill -- the perfect mix of performance and style.

Juan Martín del Potro

Del Potro will bid for his second career Grand Slam victory in the Rib Crest Crew. The simple aesthetic is highlighted by a raised V-neck design for increased coverage and flatlock seams to minimize irritation caused by chafing.

Serena Williams

Williams will debut the Pleated Knit Dress in Melbourne. The dress' stretch polyester incorporates Nike Dri-FIT material to help pull moisture away from the skin to the surface of the garment, keeping Williams dry and cool in the Australian heat. The Nike Sphere mesh has a 3-D structure that provides lightweight ventilation and keeps the product from clinging to the skin. The deep scoop in the neck and back increases mobility with a nonrestrictive fit, which is also accentuated by the merrow stitching in the pleated skirt.

Maria Sharapova

The Premier Maria Dress is a beautiful blend of style and performance befitting an athlete of Sharapova's grace and ability. The fabric features a new perforated stretch construction for enhanced cooling and mobility and a racerback design to increase support and range of motion. A shimmery finish is featured on the front that will catch light as Sharapova glides across the court. The ombre print makes a striking game-day statement.

Vika Azarenka

The current world No. 1 will step onto the court in Melbourne in the Flouncy Knit Dress. The body of the dress is made with iconic Dri-FIT fabric, with side and back panels to increase breathability and keep Azarenka dry and comfortable. The dress also features flatlock "princess" seams that reduce irritation and provide a flattering fit. A modified racerback design increases range of motion during play.

Li Na

Li Na will also benefit from Dri-FIT construction with a pique fabric that will keep her dry and comfortable during the tournament. The pintucks at the shoulder panel provide a flattering fit, and the contoured bodice seams mimic the body's natural shape. The three-button placket and elastic taping at the back reduce the potential for irritation caused by chafing, and the short sleeves have a self-fabric binding at the cuff.
