Major surprise: William and Harry are speechless when they see their Spencer cousins

Families with history are often surrounded by figures who, generation after generation, keep a particular heritage alive. In the Spencer household, that translates into style, elegance, and constant participation in social gatherings. Kitty, Amelia, and Eliza Spencer, cousins of William and Harry, are well-known participants in the world of sparkle and glamour.

Although the spotlight is usually on other members of royalty, they have gained prominence in the social circuit. Their presence at major events never goes unnoticed, and they're being invited to more and more of them. But when the three sisters appear together, it's inevitable for them to capture the headlines in the press.

Lady Kitty, a fairytale dream in aquamarine

For the Serpentine Gallery Summer Party, Kitty Spencer chose an aquamarine dress that looked straight out of a fairytale. With an off-the-shoulder neckline, sash, and a wide skirt, her look was pure fantasy. The floral embroidery added romance and a classic touch that charmed everyone.

She had already dazzled on other occasions, such as at Harry and Meghan's wedding. There, she was chosen as the best dressed by ¡HOLA! readers. Her presence now at Kensington Gardens confirmed that she's still an absolute style icon.

Lady Kitty Spencer is married to businessman Michael Lewis and is the mother of a little girl. Kitty combines motherhood and elegance with admirable ease, being a regular figure at major events.

Amelia and Eliza Spencer, the power of red

The twins, Amelia and Eliza Spencer, didn't fall behind and went all in on red, with long dresses of impeccable cut. Amelia stood out with a cape sleeve, while Eliza chose a subtle draping. Their looks reflected personality and sisterly complicity.

Their sparkling clutches and diamond jewelry elevated their styles even more, and their synchronicity once again stole the spotlight on the carpet. The Spencer effect was felt more intensely than ever, each with her own style, but all with natural elegance. Although princes William and Harry weren't present, the echo of the moment undoubtedly reached them.

Other guests went for bold choices, for example, Lady Amelia Windsor, with a fuchsia minidress and colorful platform shoes, played with a sixties aesthetic. Cate Blanchett surprised with a shell design, while Eiza González dazzled in a sheer dress. All brought their own vision of glamour, but the Spencers left an impression that's hard to surpass.
