The 37-year-old royal - who is expecting her first child in the spring - has showcased two new looks by her go-to designers Martin Grant and British favourite Roksanda during the fourth day of her 16-day tour of Australia, New Zealand, Tonga and Fiji with her husband, Prince Harry. 

The Duchess opted for a striped Martin Grant maxi dress and Castañer espadrilles during a visit to Bondi Beach, where the couple met a local surfing community group, known as OneWave, and helped to raise awareness for mental health and well-being.

The former 'Suits' actress - who was previously known as Meghan Markle before getting married in May - has had websites crashing with fans eager to get their hands on the coveted pieces the royal is pictured in.

Meghan recently stepped out in a sleeveless shift dress by Karen Gee after announcing her pregnancy, causing the label's website to crash.

The Duchess has attracted plenty of for her simple-but-chic looks on the tour and even wore a piece from her pal Serena Williams' fashion line. 

On the second day of her royal tour of the Commonwealth in Dubbo, Australia, Meghan wore a grey blazer from the tennis legend's collection. 

The royal opted to wear a double-button style blazer with patch pockets and a red-and-blue windowpane pattern.

Serena, 37, was thrilled that her friend sported her blazer - which has now sold out - and took to Instagram to reveal her joy, sharing a picture of the Duke and Duchess holding hands and smiling. 

She wrote: "The face you make when you and Duchess of Sussex Meghan have matching @serena blazers. (sic)"
