Eliza’s beach waves were parted neatly in the centre, creating a royally relaxed aesthetic that felt both modern and effortlessly chic.

Her mermaid-like locks appeared to have been styled with a crimping tool, giving them a polished yet playful texture that shimmered beautifully under the lights.

Meanwhile, her twin sister, Lady Amelia Spencer, kept things classic with a sleek, straight hairstyle that perfectly complemented her minimalist outfit.

The transformation came as a surprise to many, as Eliza is best known for her polished, structured updos and chignon buns that evoke old-school glamour.

In contrast, this looser, more undone look hinted at a subtle style evolution – one that channels a softer, more carefree energy while maintaining her signature poise.

Over the past year, both sisters have been cementing their status in the fashion world, collaborating with some of the biggest names in British luxury.

Back in June, the duo fronted a summer campaign with a prestigious British lifestyle brand celebrated for its timeless craftsmanship and luxurious leather goods.
