Sienna Miller once again shows why she’s the undisputed queen of understated British style. Spotted in London on March 11, 2025, the actress and fashion muse stepped out in a look that was both polished and relaxed, staying true to the signature vibe she’s been inspiring for nearly two decades.
She wore Gucci’s Horsebit Ballet Flats in light brown mini GG suede, a nod to the brand’s equestrian roots. She paired these timeless flats with a tailored gray double-breasted coat, a crisp white blouse, and cropped, frayed-hem jeans for a laid-back twist on classic tailoring. Oversized retro sunglasses and a soft, slouchy tote tied everything together, capturing the easy luxury she’s famous for.
From the front row at fashion shows to quick strolls through St. Pancras station, Miller’s influence on modern boho-chic style is undeniable. Her Gucci moment here reminds us that she’s still one of the most quietly powerful dressers in the industry. It’s never overdone, always iconic.
The Horsebit Ballet Flats are priced at $990 and available to purchase at Gucci.
