The relentless march of Brand Beulah! Princess Beatrice owns TEN. (And there doesn’t seem to be a royal woman who hasn’t worn the British label…)

A volunteer trip to India, where they witnessed the harsh reality of modern slavery, proved life-changing for the founders of Beulah London.

During a three-month stay in the slums of Delhi in 2009, Lady Natasha Rufus Isaacs and Lavinia Brennan taught crucial sewing skills to victims of sex trafficking.

Returning to Britain, they founded their brand the following year, driven by a commitment to creating new opportunities for these women – and they have upheld this mission ever since.

Unsurprisingly, Beulah London’s unique and uplifting initiative has received a lot of attention in royal fashion circles, with Catherine, Princess of Wales, Sophie, Duchess of Edinburgh, Princess Beatrice, Princess Eugenie and Zara Tindall all donning their graceful designs.

Even Amazon Prime’s latest film, Red, White and Royal Blue, based on the Casey McQuiston novel, is a nod to the brand.

The film, which follows the romantic relationship between the son of an American president and a British prince, stars Ellie Bamber as Princess Beatrice, complete with her Beulah London wardrobe.

But Natasha loves seeing women, royalty or not, wearing her label.

‘We are always happy when someone wears our dresses! It’s a real honor to see the Royal Family carrying Beulah and supporting smaller British businesses,” she told MailOnline.

Beulah London is almost always spotted at royal events, including Trooping the Colour, Royal Ascot and the Queen’s National Service of Thanksgiving.

The most recent sighting took place on Monday, when Princess Beatrice dined at La Loma, part of the private club Oswald’s, located in Mayfair.

She repeated her ‘Ahana’ dress in forest green and paired it with lace pumps.

The sleek fit-and-flare silhouette is a firm favorite of Beatrice’s, stocking it in four variations – along with six other designs.

A few weeks earlier, the royal family stepped out in the label’s best-selling “Christina” dress at a Buckingham Palace Garden Party.

She brought some much-needed cheer to the dreary afternoon in her charming crimson gown, with delicate buttons and a high ruffled neck.

“She looked beautiful and elegant as always,” said Natasha.

And Beatrice isn’t the only royal with a penchant for the vibrant hues of Beulah London: Sophie, Duchess of Edinburgh, and Sophie Winkleman are also keen.

At last year’s coronation celebrations, Sophie wore Beulah’s ‘Yahvi’ dress in bright coral, marking one of her best ensembles yet.

Prince Edward’s wife was the epitome of summer chic as she showed off her free-spirited dance moves and sang along to Lionel Richie’s hit ‘All Night Long’.

Sophie’s dress is made from RWS-certified wool, which aims to improve the welfare of sheep and the land they graze on. She is designed and manufactured in London, supporting British manufacturing.

Natasha and Lavinia share an unbreakable bond: their grandmothers were close friends and Natasha’s father went to school with Lavinia’s uncle.

The duo’s shared Christian faith inspired their company’s Hebrew name, which appropriately means “transition from darkness to light and freedom.”

They strive to design timeless garments with distinctive feminine silhouettes, showcasing craftsmanship from India.

Before launching in 2010, Natasha and Lavinia carefully searched for global Impact Partners who shared their purpose.

“Our vision is to create sustainable, alternative employment for vulnerable women,” explains Natasha.

‘Inspired by the beautiful colors of India, we work together with local communities, using traditional techniques, such as weaving and embroidery, which we incorporate into our collections every season.’

The duo works with NGOs, social enterprises, fair trade cooperatives and small specialty manufacturers to employ artisans in India.

Including these crafts in Beulah’s collections provides sustainable livelihoods for formerly trafficked women, who either already have the skills or to whom they provide the training and tools to develop new skills.

It’s also worth noting that Beulah London donates 10 percent of profits to charity.

Their most prominent customer is undoubtedly Catherine, Princess of Wales, who can be seen wearing several dresses from the ethical brand.

Kate has a close bond with Natasha, who has known Prince William since childhood thanks to their fathers’ friendship.

One of the most memorable outfits worn by the royal family was the ‘Ahana’ dress in soft pink.

She wore the classic fit-and-flare dress, with a mandarin collar and a waistband, in both 2021 and 2023.

The brand’s influence extends beyond British borders, with Queen Mary of Denmark leading the trend.

Mary wore the beloved ‘Ahana’ dress a year before Kate did.

Both royals also own the ‘Shalini’ navy blue geo-print shirt dress and the flattering ‘Yahvi’ dress in olive green.

Given Queen Mary’s commitment to sustainability – she is a patron of the Global Fashion Agenda and the Copenhagen Fashion Summit – it’s no surprise that she’s a fan of the London label.

Speaking about what’s in store for the brand, Natasha told us, “We have just returned from a trip to India in March where we visited Jaipur. We are always fascinated by vibrant colors and textures and draw inspiration from local markets.’

Both founders successfully manage their independent label alongside family commitments, which they consider their greatest achievement.

“Running a business while raising small children has been a real challenge, but also very rewarding!” Natasha explained.

“Our greatest achievement is that we kept going and persevering through the tough times.”
