Prince William and Kate were at the All England Club on Tuesday, watching current world No 1, Serbia's Novak Djokovic, beat Italian player Jannik Sinner, before watching British player Cameron Norrie win against Belgium's David Goffin.

To attend the day's matches, the Duchess of Cambridge wore a belted, pleated blue polka dot dress and white pumps by Alessandra Rich. She carried a co-ordinated white Mulberry Amberley bag and wore Finlay and Co sunglasses, In2 Design pearl earrings and her green and purple Wimbledon members’ pin. Kate wore the same dress to the Big Jubilee Lunch, as part of Queen Elizabeth II's platinum jubilee celebrations.
It is also reminiscent of the blue and white Jenny Packham dress she wore when leaving the hospital after giving birth to Prince George in 2013.
The couple were joined in the royal box by Kate's parents, Carole and Michael Middleton. Carole wore a grey button-down floral dress with Russell and Bromley heels and Oscar de la Renta sunglasses, and she carried a rattan handbag.
Model and presenter Alexa Chung stuck to the Wimbledonplayers' all-white dress code, wearing a three-piece linen short suit by Ralph Lauren, with black mules. Chung showed off the look with a mirror selfie taken in the club's toilets.
Lynch also chose a Ralph Lauren look, sporting a white knitted dress and blazer, with white trainers and gold jewellery.
Miller also wore a dress by the American brand, opting for an embroidered off-the-shoulder linen midi with a black belt and snakeskin heels, finishing the look with Moscot sunglasses.
Chung, Miller and Lynch were among guests in the Polo Ralph Lauren and British Vogue hospitality sections. They were all dressed by the brand and sat with the magazine's editor, Edward Enninful.
Designer Vera Wang made a statement in an all-black look, subverting Wimbledon's on-court guidelines. She wore a blazer over leather trousers with platform heels.
Actress Gugu Mbatha-Raw wore a Polo Ralph Lauren navy patterned silk shirt and trouser set with a cream bag from the brand.
Also in navy was Bridgerton's Charithra Chandran, who wore a denim co-ord set when she was hosted by Jaguar at the championships. She attended with co-stars Martins Imhangbe and Adjoa Andoh.
Imhangbe wore a striped Labrum suit over a plain white T-shirt by the London menswear brand, with Stephen Webster jewellery. Andoh wore a pale yellow shirt dress.
