PIctured here at the US Open, Stosur wears the new Sleeveless Stretch Pique Striped Dress in Eclipse Blue by Lacoste, $135. White and ultraviolet purple color blocking is added in discreet doses and in ways that don't add the illusion of weight to a body.
See ya drawstring dress. This one is a BIG improvement.
Extras. The jersey tennis panty is $40 in white. The visor does not appear to be available in the US and there is a cute fleece zip that goes with it.
Based on a sample I checked out the dress fabric is a performance poly blend (sewn in label says it is). Lacoste's site says it's mostly cotton* (but it doesn't feel like it). I like a made-for-action fabric better anyway.
That eyewear! Sam is wearing Oakley Enduring frames ($180 to start) with Positive Red Iridium lenses (available to public via custom order or by buying the accessory lenses). The lenses adjust to varied light conditions automatically. Sam's lenses are also polarized to cut glare by 99%.
*9/13 Post update: Lacoste has confirmed that the fabrication of the dress is indeed 93% polyester/7%elastane.
