The Spencer sisters performed in stunning colour-coordinated red ensembles as they attended the Melbourne Cup.

Lady Amelia Spencer and Lady Eliza Spencer, Princess Diana’s nieces, were invited to judge the entrants in the racing event’s Fashions in the Field competition.

The socialite twins, both 31, looked effortlessly chic in matching dresses, which they teamed with understated headpieces.

Hundreds of people enter Fashion in the Field every year in the hope of being crowned ‘Best Dressed’ and ‘Best Suited’. It takes place before the start of the horse race.

The Melbourne Cup horse race at Melbourne’s Flemington Racecourse has been held on the first Tuesday in November since 1876.

Lady Amelia wore a short skater style dress with a sweetheart neckline and short sleeves.

She paired the dress with red stilettos and a floral headband, while her blonde locks were pulled back in a ponytail.

Meanwhile, Lady Eliza opted for a red, ankle-length, off-the-shoulder dress, with a slit at the front.

To complete her outfit, Lady Eliza wore a thin gold headpiece that fell over her face and a pair of ‘barely there’ heels. She wore her hair in a sleek style, tucked behind her ears.

Both sisters kept their makeup clean and minimal, opting for a natural pink lip color and nude eye makeup.

The twins’ appearance comes after they attended a fashion show celebrating the 50th anniversary of designer Marc Cain GmbH in Bodelshausen in September.

And it looks like the Spencer sisters are into color coordination, as they were both pictured in pink ensembles at the time.

Amelia lit up the room in bright pink culotte pants and a matching blue and magenta silk blouse that was tucked in at the waist.

As an accessory, she held a bag that touched her pearly white manicure.

Elsewhere, Eliza was the picture of sophistication in a pastel pink dress with cape-like detailing on the shoulders.

She added a touch of glitter and paired the simple yet elegant dress with a silver clutch and heels.

They sat front row at the fashion show and were joined by Diane Kruger, who they shared smiles with during the event.

Their outing came after the Spencer family celebrated the 26th anniversary of Princess Diana’s death the day before, on August 31.

Lady Eliza previously admitted that neither of the twins had any idea of ​​Diana’s impact on the world until years after her death.

“We always knew her as our aunt,” she told Tatler in 2021, adding that she remembers her as “incredibly warm, motherly and loving.”

‘Growing up in South Africa, I had very little idea of ​​how important she was in the world until I was much older… She always made an effort to connect with us as children and had a knack for reading the hearts of children.’
