Nike has unveiled the US Open 2009 outfits of their tennis players during the Nike’s US Open challenge in New York.
Maria Sharapova's day dress will be dusty-pink with fluorescent green shoulder straps and piping. Of course, the Russian will have a matching visor and a jacket.
The night version of the dress will be a combination of navy blue, almost midnight, and silver color blocks and piping. A jacket with oversized hood will make Sharapova warm during cold evenings.
Additional info: Sharapova will be wearing Tiffani & Co. earrings designed by Frank Gehry.
Serena Williams was wearing this Nike Women's Athlete Open Dress for Nike's US Open challenge in New York, so I would say it's confirmed that her US Open outfits will be the following.
The pink dress is for the day, the black one is for night sessions.
