Duchess of Westminster looks beautiful as she reemerges in V-neck sundress

The Duchess of Westminster has largely kept a low profile after giving birth to her daughter Cosima in July 2025.

Making a rare exception for the re-opening of Grosvenor Square on 13 July, Olivia (nee Henson) brought the sunshine in a lemon yellow dress from Roland Mouret. The daring low V-neck was balanced with long sleeves and a midi length, while the belt accentuated Olivia's figure and the neck scarf modernised the look.

According to Royal British Fashion, she teamed the frock with pointed-toe Manolo Blahnik mules, gold hoop earrings and her sentimental engagement ring.

Family life

She was joined by her husband Hugh Grosvenor, 7th Duke of Westminster, who inherited the Grosvenor estate – now worth an estimated £10.6 billion, including 300 acres of land in London's Mayfair and Belgravia – from his father in 2016. 

The sustainable food and drinks professional and King Charles' godson announced their engagement in 2023, but Olivia did not show off her ring. The couple tied the knot on 7 June 2024 in front of a star-studded guest list, including close friend Prince William.

The high-profile occasion was the first time royal fans got an idea of the Duchess' minimalist but striking style. She wore a gown by Emma Victoria Payne's bridal atelier EVP featuring a scalloped-edge neckline, a bias-cut skirt, gathered sleeves and a keyhole back.

Olivia and Hugh, who is Prince George's godfather, welcomed their first child in July 2025, and they embraced their baby bubble for several months away from the spotlight. 

Glamorous mum wardrobe

Making a glamorous return for the Chester FC Community Trust, the new mother looked resplendent in a summery yellow cardigan from Zara, which cost a bargain £29.99, and a suede maxi jacket in chocolate brown.

Despite only marrying into the royal family two years ago, Olivia has cemented her place as a fashion icon, following in the footsteps of the Princess of Wales.

Kate has also donned numerous Roland Mouret dresses over the years, including her cream boucle dress at Peter and Harriet Phillips' wedding in June, and her red structured summer dress for the 2026 Wimbledon women's final.
