Princess Diana’s nieces never fail to impress with their sense of style as they graced Paul Costelloe’s London Fashion Week show on Friday September 13.

This London Fashion Week marks Paul’s 40th year with the event showcasing fun mixes of textures and pastels, as also demonstrated by the stylish pair.

Lady Amelia Spencer, 32, dazzled in a brown tweed collared jacket with buttons down the front, paired with a matching brown tweed skirt.

She accessorised the look with a pair of black heeled boots and her signature blonde tresses were swept back.

Lady Eliza Spencer, 32, looked equally divine in a white high-collared jacket with round buttons down the front, and paired the jacket with a white rose-detailed short skirt.

Finishing the look, she wore metallic, silver heels, and a shiny metallic silver clutch bag.

Meanwhile, Paul’s Spring/Summer 2025 collection Le ciel est bleu (the sky is blue) was packed full of pastel colours and models wearing a mixture of textures and astel shades during the runway show.

The SS25 collection also marked a first for the designer as a selection of wedding dresses has been included in the range.

Also seen at the show was presenter and influencer Olivia Cox and Una Healy from the girl band The Saturdays.

The twin sisters, 32, who are the nieces of the late Princess Diana and daughters of Earl Spencer, both cut sophisticated silhouettes.

The identical pair added to their matching beauty glow by using a rosy pink blush, black eyeliner and dusky pink lipstick to their look.

The aristocratic twins are frequenters of the front row at fashion weeks and often prove their sartorial status by stepping out in ‘same but different’ outfits.

The twins are the daughters of Charles Spencer, 9th Earl Spencer, and his first wife, Victoria Lockwood. The former couple are also parents to Lady Kitty Spencer and Louis Spencer, Viscount Althorp.

This makes Amelia and Eliza the first cousins of Prince William and Prince Harry.

Despite being split in their support for Harry and William, since Harry stepped down as a working royal, Prince William‘s maternal cousins, Lady Amelia Spencer and Lady Eliza Spencer, were seen supporting their cousin at a fundraising gala in February for London’s Air Ambulance Charity.
