Bethanie Mattek-Sands joined forces with Alex Noble, known for designing many of pop star Lady Gaga's outfits, to create this 2011 Wimbledon pre-party dress inspired by and created from tennis balls.
Designer Alex Noble must have had some extra tennis balls lying around, as he created this jacket for Bethanie Mattek-Sands to wear on court at the 2011 Wimbledon Championships.
