Just a quick look here at what Nike had planned for Ms. Serena at Roland Garros. It's a fitted and very pretty pink number with flirty asymmetrical ruffled tiered bottom, $90 USD; another good mix of power and pretty. Even the colors contrast that way, gridiron and cerise pink. Shoes are the Nike Mirabella.
Her Twitter feed indicates she's working on coming back to the game. No official word at the moment though.
