When it comes to British style icons, the Princess of Wales and Geri Horner might not seem like the most obvious duo.
One is a regal, polished princess with a wardrobe that embodies timeless sophistication. The other is pop royalty who in her Spice Girls heyday was best known for her iconic Union Jack mini dress and chunky blonde highlights.
But in recent years, Geri Halliwell, now Horner after marrying Formula One Red Bull Racing boss Christian Horner, has undergone a style transformation that has placed her firmly in Kate’s sartorial space.
Over the years they have regularly stepped out in strikingly similar outfits that showcase their shared love of classic, tailored silhouettes and ultra-feminine details.
From elegant coats and classic dresses to immaculate monochrome ensembles, Geri appears to have taken a page straight out of Kate’s style handbook.
At this year’s Commonwealth Day service, the former Spice Girl turned heads in a Jenny Packham dress. Featuring delicate black piping and a structured fit, the frock bore a remarkable resemblance to another Packham number worn by Kate the year before at Trooping the Colour.


Geri Horner epitomises modern elegance as she graces the Commonwealth Day service at Westminster Abbey wearing a white Jenny Packham frock adorned with grosgrain trim and delicate crystal embellishments. With its striking black piping at the waist and collar it is reminiscent of the dress the Princess of Wales wore to Trooping the Colour in 2024 which was also designed by Jenny Packham


At the Cannes Film Festival in 2023, Geri dresses for glamour in a one-shoulder gown from Erdem’s bridal collection. Earlier in 2023 at the BAFTAs, Kate Middleton also oozes sophistication in an Alexander McQueen one-shoulder gown featuring the same flattering asymmetric neckline and oversized bow


Stepping out for Anzac Day in 2022, the Princess of Wales wears a cream Alexander McQueen coat dress and a tweed halo headband by milliner Jane Taylor, a design that has since been spotted on Geri Horner at the 2024 Commonwealth Day


Both Kate and Geri prove tonal dressing is the ultimate formula for sophisticated glamour when dressed in head-to-toe cream ensembles. The Princess of Wales has long been a fan of monotone looks, and at her 2023 Together at Christmas carol service she embraced winter whites in trousers by Holland Cooper and a coat by Chris Kerr. The timeless combination has also been spotted on Horner who chose the tailored combination at Global Studios in 2018


The Princess of Wales chose a sleek and refined look in 2012 as she steps out in a figure-hugging Roland Mouret frock for an engagement at the Thirty Club. The fitted cream dress, with its modest high neckline and long sleeves, is the epitome of understated glamour, skimming Kate’s frame. Over a decade later Geri Horner mirrors the elegant aesthetic in 2023 at her Rosie Frost book launch wearing a similar full-length Edeline Lee gown


Kate Middleton made headbands cool again, and arguably her most famous headband has to be a bespoke creation by Jane Taylor she wore to Prince Louis’s christening back in 2018. Featuring a thick platform and striking appliqué flowers stitched on the top, her crowning glory style was repeated by Geri Horner in 2024 as she accompanied her husband to Buckingham Palace

Monochrome tailoring is a style straight out of Kate Middleton’s fashion rulebook and in 2022 she debuts a similar co-ordinating suit with ankle length trousers by Alexander McQueen to attend the Birmingham Commonwealth Games
Given that Jenny Packham is one of Kate’s go-to designers, it’s no surprise Geri is also drawn to the brand’s refined, elegant aesthetic.
The Princess of Wales has long favoured Packham’s creations for some of her most high-profile engagements, including royal tours and red-carpet appearances.
Geri seems to be following suit, adding the British designer’s signature pieces to her own wardrobe, likely in a bid to emulate Kate’s regal elegance.
The similarities between Kate and Geri’s fashion choices don’t stop at clothing. When it comes to accessories, they are equally in sync.
At the 2024 Commonwealth Day service, Geri completed her outfit with a Jane Taylor headband featuring a large black bow, a style that Kate had previously worn on Anzac Day in 2022.
The royal-approved milliner has been a favourite of Kate’s for years, with the princess frequently turning to her designs for formal events. Now, Geri appears to be taking notes, incorporating the same refined headwear into her own wardrobe.
In a dramatic departure from her Spice Girls days, Geri has recently revealed she has embraced an all-cream wardrobe, citing simplicity and elegance as her key reasons for the switch.
Gone is the iconic Union Jack dress and bold colours, as she turns her commitment towards the power of monotone dressing.
This is a fashion philosophy that Kate also follows in head-to-toe tonal looks that exude sophistication, understanding the impact of a well-executed monochrome outfit for an approach to dressing that is all about understated luxury.
Geri Horner’s transition from pop star to polished style icon has placed her firmly in Kate Middleton’s fashion territory, and as the undeniable similarities between her and the Princess of Wales continues, so too does their status as secret style sisters.

Both ensembles were understated yet far from boring, proving the power of good tailoring and a tone-on-tone colour palette.
