Victoria Beckham's fashion label doubles its revenue after Kendall Jenner, Queen Letizia, Phoebe Dynevor and Amanda Holden were spotted wearing her £890 dress

It's the £890 Victoria Beckham dress that has been worn from A listers ranging from Spain's Queen Letizia to Bridgerton's Phoebe Dynevor.

And now the Mail can reveal it has been the fashionista's secret to doubling the revenues of her once troubled label, posting today an impressive 52 per cent rise in her sales.

Victoria, who turned 50 in April, is said to be 'thrilled' at her turnover this year and the frock has sold so well that she has put it all down to the Bella - a gathered waist midi dress which comes in multiple colours including black, royal blue, red, ivory. There is also a 'mini dress' option.

Coined her 'cult item' the dress has been flying off the shelves since it launched in her spring/summer 2023 show. 

In fact, one in ten of her the former Spice Girl's online sales is the outfit.

A source close to fashion designer said: 'Victoria has worked so hard on her label, it has been tough at times but she is so happy it is now going from strength to strength. It is so lovely that it has happened in what is such an exciting year for her, what with her turning 50 and celebrating 25 years of marriage. It's all so joyous.'

While Victoria is always a staunch ambassador for her own brand and has worn the Bella frock numerous times, in May 2023 Queen Letizia of Spain, 51, wore it to a Buckingham Palace reception on the eve of King Charles's Coronation.

American supermodel Kendall Jenner, 28, wore the midi for a party at Nobu in Dubai, styling it exactly as her friend Bella Hadid, 27, wore it on the runway, with black leather gloves.

And in January this year Pheobe, 29, wore a cream version for the BAFTA Tea Party in Los Angeles, while Amanda Holden sported a purple one at Ascot last year.

It is the first time Victoria's clothing has been praised for its success. When her accounts were published in December they showed that it was her popular makeup item, the £30 Satin Kajal Liner and her £1,050 Chain Pouch Bag which were said to be behind the label's impressive results.

Launched in 2008, despite its famous founder, the brand has struggled to make any money.

Auditors had warned that it risked going bust without further financial support from shareholders, which include the Beckhams and private equity firm Neo Investment Partners.

The luxury label has borrowed more than £30million from other parts of the Beckham business empire over the past 15 years.

However, last year's results mark a turning point where the group became profitable.

In 2023 the delivered its third consecutive year of high double-digit growth as revenues rose by over half, to £89.1million  in 2023 from £58.8million in 2022

With its flagship store in Mayfair, London, the former Spice Girl has displayed much of her work at Fashion Weeks with the most recent one being in Paris in March.

In an interview with Vogue France in October 2023, she revealed the brand had turned a profit saying 'this is just the beginning, I have lots of ambitions and I work hard to achieve my goals.'

She went on: I never wait for things to just fall into my lap. It's such an exciting time. This year, we made a profit! This takes time, especially for an independent brand. My perfume isn't a license - I own it.

'Now that I have laid down the groundwork for the house, the real work can begin.'

In 2020, it was revealed by The Mail on Sunday that Victoria was to use the government's furlough scheme to pay her staff during the pandemic - despite her and husband estimated £360million fortune.

However, after much criticism, she did a U-turn, meaning UK tax payers were saved from funding her employees' salaries.

In accounts submitted in 2021, auditors warned of 'significant doubt' about Victoria's fashion company's ability to continue operating when it was reported the company had racked up debts of more than £46million since it launched.
