All attention was on Serena Williams as she earned her 22nd grand slam title today, but discerning eyes would have also noticed the leading ladies in the stands who brought their sartorial best to Wimbledon this week. Kate Middleton, Duchess of Cambridge, wore a yellow shift dress on Thursday, and the following day, her sister Pippa sported a purple floral-printed sun dress. Ellie Goulding, meanwhile, went the retro-glam route in an off-the-shoulder cream sheath by the British designer Suzannah. Model Irina Shayk brought model-off-duty cool with a tuxedo blazer and jeans (and accessorized with Bradley Cooper), but Sienna Miller stole the show in a preppy orange dress by Burberry.
