Some celebrity reveals feel planned, polished and perfectly timed, and then there’s Sienna Miller, who has always specialised in the kind of nonchalant glamour that somehow feels both spontaneous and strategic. After keeping a noticeably low profile these past few months, she stepped onto the 2025 Fashion Awards red carpet at the Royal Albert Hall with the kind of quiet confidence that only comes from knowing the entire room is about to gasp. And they did. The actor is expecting her third child, her second with Oli Green, and she chose this particular night to let the world in.
If there’s a better stage for a baby bump than a major fashion gala, we haven’t found it. Sienna has done this before, of course. Her 2023 appearance at Vogue World: London, where she floated in wearing a sculptural Schiaparelli puffball skirt and a cropped ruched shirt, remains one of the most memorable modern pregnancy moments. Schiaparelli’s Daniel Roseberry called it an honour, and her then-stylist Harry Lambert predicted headlines. He wasn’t wrong.
This time, she turned to Givenchy. The gown — sheer, weightless, and quietly enchanting — felt like a love letter to her early boho era. Think a little Y2K wistfulness, a whisper of Stevie Nicks, and just enough undone waves by Sam McKnight to remind everyone that red-carpet glamour doesn’t always need to be lacquered and loud. It was Sienna at her most Sienna, the version that once convinced an entire generation to buy coin belts and cork wedges with absolute sincerity.
And the crowd noticed. At an event built to celebrate designers and industry visionaries, the night gently tilted in her direction. Because whether she’s wearing a naked dress, a fringed jacket or an unplanned glow courtesy of impending motherhood, she has a way of making personal style feel like a cultural cue. When she steps out like this, everyone starts searching for their own version of the look — or their own explanation for how she makes pregnancy dressing appear this effortless.
There will be think pieces about the gown, the glow, the return of ethereal sheer dresses. But on this particular evening, the feeling was simpler. It was about Sienna choosing her moment, and doing it with the soft kind of confidence that makes the rest of us rethink every time we’ve ever called maternity wear uninspired.
