What with the tropical temperatures in the U.K. this week, the vast majority of the female population has been drifting through recent days in variations on summer’s by now ubiquitous boho skirt. Sienna Miller, being something of an architect of modern boho style, is presumably no different.

That was certainly the case at Wimbledon on Sunday, where the long-time tennis fan arrived to see Carlos Alcaraz and Jannik Sinner battle it out for the men’s singles title wearing an outfit that would have fit in equally well at the new Soho Farmhouse Ibiza as at SW19. Miller, who—along with the likes of Lila Moss and Theo James—was hosted by Ralph Lauren at Wimbledon, chose a floaty, crinkle effect maxi skirt by the brand, worn with a gently cropped crochet top and white kitten-heeled sandals.

And wait… is that a hint of a Glastonbury-in-the-early-Aughts coin belt we spy? Okay, not quite. But the metallic accents on her Western-inspired accessory certainly hark back to those photos of Sienna’s still-influential Worthy Farm wardrobe.

Miller was one of a whole host of famous faces in the crowd on finals day, chief among them the Princess of Wales—a patron of the All England Tennis Club—who chose a Roksanda dress in a vibrant shade of blue to take her seat in the Royal Box, accompanied by Prince William and two of their children, Prince George and Princess Charlotte.
