Princess Diana's nieces certainly inherited their royal aunt's enviable sense of style, as their look on Wednesday, October 16 proved. Lady Kitty Spencer and her twin sisters, Amelia and Eliza Spencer, hit the red carpet in coordinated icy blue gowns to support their cousin Prince William at the Center Point Awards in London.

It-girl Kitty, who had a 2022 wedding that blew our fashion minds, looked stunning again in a pale blue lace Dolce & Gabbana gown with an intricate Venetian scene on the skirt.

The corseted long-sleeved dress, part of the brand's Fall 2021 Alta Moda collection, appears to be covered in sequins, but according to the designer's rep, the stunning Venetian canal design is actually cross-stitched into the gown. She accessorized with a furry white clutch bag and jewelry that appeared to be earrings coordinated with a citrine and topaz necklace.

As Dolce & Gabbana's global ambassador, Kitty has a long association with the fashion house, having worn five different dresses by the designer for a glamorous Italian wedding (but sadly, no Spencer tiara). She has also modeled for the brand on numerous occasions, making her look at Wednesday's awards a natural choice.

Meanwhile, identical twins Amelia and Eliza Spencer, who recently appeared in the pantsless trend, are fashion stars in their own right. Like their older sister, they also opted for an icy blue look for the Center Point Awards, choosing gowns from royal brand Temperley London.

Lady Amelia, once voted the most beautiful royal family by Tatler magazine, wore a silky, vintage-inspired look. The soft ruffled bodice recalls one of Princess Diana's iconic dresses of the 1980s. But the royal niece put a modern twist on that romantic dress, creating a collar-like neckline with intricate silver and blue beading.

Like Kitty, Lady Amelia wore her hair in a twist-up for the occasion, revealing fan-shaped diamond earrings. She also added sparkle to her bag and shoes, wearing silver pumps covered in crystals and carrying a glittery pale blue clutch.

Eliza wore a temperate gown of the same color and fabric as her twin. The low neckline was perfect for a sparkling diamond pendant, which she paired with sparkling earrings, silver platform sandals, and a crystal-studded clutch.

However, Lady Eliza mixed up her good looks at the awards ceremony by wearing her hair down in soft waves.

This is not the first time the Spencer sisters have supported their cousin Prince William at an event; Amelia and Eliza wore glittery black and white looks to the London Air Ambulance Gala earlier this year. However, this was a particularly exciting outing for the three of them, as they rarely go out together.

William, on the other hand, rocked a blue velvet tuxedo jacket as he gave a moving speech Wednesday evening in support of the homeless charity Centrepoint. Princess Diana would be proud.
