The Duchess of Cambridge wore her favourite New Zealand fashion designer on her first public appearance since spending a few days in self-isolation, following a Covid-19 scare.

Kate Middleton attended the Wimbledon women's final wearing a dress by Emilia Wickstead, a Kiwi fashion designer whose pieces had previously been worn by the duchess.

The royal had been in quarantine since Friday, July 2, after she had been in contact with someone who later tested positive for Covid-19.

According to Buckingham Palace, the duchess did not experience any symptoms but followed government guidelines and self-isolated at home.

Middleton, who is a patron of the All England Lawn Tennis and Croquet Club, was back to Wimbledon yesterday, where she presented Australian Ash Barty with her first Wimbledon winner's plate.
