Kate Middleton has been noticeably absent from the Wimbledon Championships so far this year with her parents and sister Pippa ubiquitous in the past week. However the Duchess made up for it today (July 7) as she brightened up the court in a recycled vibrant yellow Roksanda shift dress with white panelled inserts on the skirt and arms to watch Serena Williams play Elena Visnina in the semi-finals of the 2016 championships.

The shift dress retailed at £900 originally and was a key part of the Duchess's Royal tour wardrobe to Australia in 2014. It achieved brief 'notoriety' when Prince William affectionately said that she 'looked like a banana' when she first wore it to the Sydney Opera House.

For her first outing at Wimbledon 2016, Middleton also eschewed her usual LK Bennet nude pumps in favour of a more sleek stiletto design by Rupert Sanderson which retails for £425.

Roksanda has been a firm favourite of the Duchess of Cambridge for some time and this is by no means the first time she has chosen the British brand for an official occasion, nor is it the first time she has recycled one either. Middleton wore a powder blue shift to the Queen's 90th celebrations recently and has also been photographed many times in a favourite grey silk asymmetric design from the designer proving that not only is the Duchess not frivolous with her clothing choices but that Roksanda is a worthy investment brand to buy into.

The Serbian-born designer studied at London's Central St Martin's and has her business firmly based in the UK. Her clean, sophisticated and unfussy aesthetic has proved popular with everyone from Michelle Obama to Gywneth Paltrow.

Aside from keeping up appearances in the royal box, Middleton also went behind the scenes at the lawn tennis hub in SW19 meeting with the ball boys and girls ahead of the match.

The Duchess was also seen chatting to Wimbledon chief Phillip Brook before settling down in the front row of the royal box to watch Russian player Elena Visnina take on Serena Williams.

They were in for a brief game as Williams beat Vesnina in just 48 minutes 6-2 6-0 on Centre Court to cruise into the final.
