Bursting onto the pop scene in 1994 as one-fifth of the Spice Girls, Geri Horner (née Halliwell) has been in the spotlight for more than 25 years.

During that time the showbiz star – who turns 50 on August 6 – has been quite the fashion chameleon, often switching up her style to suit her career and personal life.

To mark the milestone birthday, we take a look back at her remarkable fashion evolution…

1990s: Ginger Spice

Taking the pop world by storm in the mid-1990s – alongside Spice Girls bandmates Melanie Brown, Melanie Chisholm, Emma Bunton and Victoria Beckham – Horner was given the nickname ‘Ginger Spice’ in honour of her fiery red hair.

The 20-something pop star was all about attention-grabbing outfits, often sporting the brightest, loudest ensembles of the group.

Her most iconic Spice Girls look is undoubtedly the extremely short Union Jack minidress she donned to perform at the 1997 Brit Awards, teamed with bright red platform boots.

Causing widespread shock, Horner quit the phenomenally successful girl band in 1998 and quickly set about reinventing herself.

Unveiling a sleek new look later the same year, she sang happy birthday to Prince Charles at his 50th birthday bash, wearing a stunning midnight blue strapless gown with a huge skirt.

2000s: Solo star

Embarking on a solo pop career, the singer formerly known as Ginger Spice embraced all the biggest Noughties trends, incuding halter tops, low-rise jeans and mini kilts.

Swapping her bright red hair for honey-blonde locks, the pop star’s off-duty style was decidedly more demure, and on the red carpet she favoured glamorous, figure-hugging gowns.

In 2007, the Spice Girls announced they would be reforming. Horner, who had given birth to her first child, Bluebell Madonna, the previous year, looked somewhat out of place at the reunion photocall, wearing a floaty white maxidress – while the other members chose edgy black and red outfits.

2010s: Olympic glory

Horner’s style continued to evolve in the 2010s, and she experimented with the blonde, bronzed babe look.

The Spice Girls returned to the spotlight once more with their epic performance at the London 2012 Olympics closing ceremony. Ginger Spice harked back to her iconic Brits look with a red minidress, complete with Union Flag bustle.

In 2015, she chose British designer Phillipa Lepley to create the lace-trimmed bridal gown for her wedding to Red Bull Formula 1 boss Christian Horner.

Now: Minimalist chic

Nowadays, Horner will wear any colour… as long it’s white. Or cream. Or ivory. Rarely pictured in anything other than these pale hues, Horner has found her fashion groove, and it’s a far cry from her Spice Girls style.

The mum of two (she gave birth to son Montague in 2017) is all about luxury loungewear, floaty blouses, swishy skirts and white jodphurs (the long-time equestrian enthusiast owns several horses).

Horner loves the all-white look on the red carpet appearances, too, often styling a chic column gown with an elegant updo and bold red lip.
