To watch Serena Williams beat Elena Vesnina on the tennis court, the Duchess donned a sunny Roksanda dress, pearl earrings by Soru Jewellery, heels by Rupert Sanderson and her trusty Ray-Ban Wayfarer sunglasses.
This isn’t the first time the Duchess has been spotted in the yellow midi-dress, which made its debut in 2014 during her Royal Tour of Australia.
Designer Roksanda Ilincic, who runs the eponymous brand Roksanda, custom-made the dress for the Duchess by reversing the colours on her classic Ryedale dress (priced at £950, and sadly sold out).
The dress is affectionally known by fans as the ‘banana dress’.
When the the Duchess arrived in Sydney wearing the design, she reportedly told a woman complementing her outfit: “William said I look like a banana”.
As if we needed another reason to love her.
