Just a quick look here at Maria Sharapova's tennis dress for the Paris Open courts. It's called the Nike Women's Summer Premier Maria dress. All performance, molded cups in the built-in bra and no-sew seams make for a statement look that really moves without chafing anywhere. $110 USD.
The only colorway is this one, canyon purple with pure violet side panels and volt straps. Thin straps tend to cut in and bother my shoulders but haven't tried this one myself. Knowing Nike, they've worked this out.
