Sienna Miller’s pregnancy reveal stuns Fashion Week as the actress showcases her baby bump in an ethereal Givenchy gown at London’s Royal Albert Hall.
Sienna Miller has been keeping a low profile, and the reason has come to light. The actress, now eight months pregnant, is expecting her third child, her second with partner Oli Green. It seems she decided to reveal the news at the 2025 Fashion Awards, held during London Fashion Week, creating one of the year’s most memorable red carpet moments.
It’s a smart way to grab attention. Showing off a baby bump on the red carpet is both charming and effective, and it’s been done before. At the Vogue World show in London in 2023, Miller, who was pregnant at the time, lit up the red carpet. She wore a Schiaparelli outfit featuring a voluminous white skirt and a cropped top gathered at the waist. It was hands-down the most talked-about look of the event. Schiaparelli’s creative director, Daniel Roseberry, said, “We’re honored by her selection.” Her then-stylist, Harry Lambert, added, “It deserves the headlines!” That bold and artistic cloud-like outfit delivered on that promise.
At the 2025 Fashion Awards, Miller chose an outfit that highlighted her bohemian roots rather than a traditional high-fashion look. She wore an ethereal sheer gown, which was the 37th piece from Sarah Burton’s spring 2026 Givenchy collection. The design mixed a touch of early 2000s nostalgia with a heavy nod to Stevie Nicks, complemented by an oversized black blazer draped elegantly over her shoulders. Sam McKnight completed the look with his signature messy-glam hairstyle. This style of Sienna Miller’s is a timeless choice that many across Britain have imitated, reminiscent of the iconic fashion in “The Devil Wears Prada.”

At the famous Royal Albert Hall event, Miller caught everyone’s eye. Nobody else has the same power to encourage people to try cork wedges, coin belts, or pregnancy outfits that go beyond the usual maternity styles. Others follow where Miller leads because she sets the trends. She looked great because of her confident demeanor and radiant pregnancy glow, proving that maternity fashion can be both comfortable and chic. Even her nails were perfectly manicured, as if she had just stepped away from a nail art station.
Miller’s fashion choices have always been influential, from her boho-chic days to her more polished red carpet appearances. Her ability to effortlessly blend high fashion with a touch of bohemian flair has made her a style icon for many. This latest appearance at the Fashion Awards is no exception, showcasing her evolving style as she once again embraces motherhood. It’s worth noting that Miller’s keen eye for fashion might be a family trait, as she has a fashion designer sister who has made waves in the industry.

Gone are the days of shapeless dresses and oversized gym gear as the only options for expectant mothers. Miller’s bold choices demonstrate that pregnancy can be a time to embrace and elevate one’s personal style.
It’s worth noting that Miller has navigated her personal life with grace, maintaining positive relationships even with her ex, Tom Sturridge, with whom she co-parents her first child. This maturity and poise are reflected in her fashion choices, which seem to grow more refined with each public appearance.
