Lady Amelia and Eliza Spencer – Princess Diana’s nieces – strike a pose in co-ordinating outfits at Madrid Fashion Week

The flaxen blonde Spencer sisters enjoyed a winter trip to Madrid this weekend to attend the Mercedes-Benz Fashion Week in the Spanish capital.

Lady Amelia Spencer and Lady Eliza Spencer chose to coordinate black and gold couture to attend the Casademunt by Maite fashion show at IFEMA Madrid.

The 31-year-old twins, Princess Diana’s nieces, wore their blonde hair sleek and loose for the fashion event, and both wore outfits made from the same fabric.

Lady Amelia wore a black and gold check skirt suit, with a matching oversized handbag and brushed gold earrings.

Meanwhile, her twin brother opted for trousers in the same fabric, along with a chic gold shirt and a smaller version of the handbag. Both wore matching stiletto heels.
