Sienna Miller chose the most glamorous stage imaginable to share her most intimate news. After weeks of keeping an unusually low profile, the actor made a luminous return to the spotlight at the Fashion Awards 2025—arriving in a cloud of sheer Givenchy and confirming she is expecting her third child, her second with fellow actor Oli Green.
It was a reveal worthy of fashion folklore. Miller has long understood the power of a red carpet moment, and this one echoed the unforgettable scenes of Vogue World: London 2023, when she became the night’s undisputed headline in a Schiaparelli puffball skirt and sculpted cropped shirt. That look became an instant cultural artifact; her stylist at the time, Harry Lambert, famously insisted: “It deserves to make headlines.” Indeed, it did.
For her triumphant return at the Royal Albert Hall, Miller embraced her bohemian signature with renewed, ethereal elegance. Her Givenchy spring/summer 2026 gown—diaphanous, nostalgic, and subtly enchanting—evoked the dreamy spirit of Stevie Nicks through its ’00s-lilted sheerness and effortless undone glamour, polished to perfection with Sam McKnight’s artful tousling.
The effect was quintessential Sienna: romantic, rule-breaking, and wholly irresistible.
And while the evening celebrated the industry’s brightest talents, there was no mistaking who commanded the room. Miller has, for two decades, possessed a singular ability to spark trends with nothing more than a well-placed coin belt or a pair of cork wedges. Her maternity-era looks, too, have famously defied convention, carving out a space far from the confines of traditional pregnancy wear.
If history is any indication, her latest appearance will set off a fresh wave of sheer-dress obsession—and perhaps a global search for the secret behind that incandescent pregnancy glow.
