Sienna Miller lit up The Fashion Awards in London with a luminous pregnancy reveal and a look designed for comfort and impact. Here is exactly what stood out.
London paused for a beat when Sienna Miller stepped onto The Fashion Awards red carpet at the Royal Albert Hall on December 4, 2023, revealing a baby bump with serene confidence. The British American actor, 41 at the time, arrived with a quietly spectacular look that framed her silhouette without fuss, turning the annual British Fashion Council gala into a maternity style headline.
Sienna Miller is expecting her second child with actor and model Oli Green, confirming a new chapter more than a decade after welcoming her first daughter, Marlowe, in 2012. The appearance landed at a high visibility moment for the industry, with cameras trained on a sculptural skirt and a minimal crop top in a soft tone that let the message speak for itself.
Sienna Miller at The Fashion Awards 2023 : what happened on the carpet
The main takeaway arrived instantly. Sienna Miller did not hide or overplay her pregnancy. She chose a simple palette, a clean neckline, and a painted face that stayed light. Jewellery stayed delicate. The silhouette read modern, not costume, and that balance carried across photos within minutes of her arrival.
The event setting added weight. The Fashion Awards is the British Fashion Council’s annual fundraiser hosted in London, and the 2023 edition took place inside the Royal Albert Hall, a venue known for scale and ceremony. Against that grandeur, Sienna Miller introduced ease into eveningwear, an approach many expectant guests quietly hope to achieve.
There was context too. Sienna Miller shares an 11 year old daughter with actor Tom Sturridge, and the new baby with Oli Green marks a fresh family timeline. With a 14 year age gap between Sienna Miller and Oli Green, the couple has addressed curiosity by staying low key and letting work and life speak in pictures rather than in statements.
Pregnancy style decoded : why this look worked on a big stage
Red carpet maternity dressing can slip into extremes. Some outfits overcompensate with structure. Others hide the silhouette and lose personality. Sienna Miller navigated that middle ground. She went for a cropped top that revealed the bump without strain, paired with a voluminous skirt that moved easily and kept proportions clean.
The choice aligned with a few reliable principles. Fabrics that drape rather than grip give comfort under lights. A softer hue photographs well against deep red backdrops. And a single focal point makes images calmer. Sienna Miller kept the eye on the bump and the sculpted skirt, leaving hair and makeup gently polished.
There is a human layer worth stating. People do not dress the same through a pregnancy, and pressure around spectacle can feel heavy. Sienna Miller’s appearance suggested a different mood. No shouting, no awkward gimmick, just a calm reveal that respected the moment and the venue. It felt glamourous, and also wearable outside that one night.
Beyond the flashbulbs : Oli Green, family timeline, and what comes next
Sienna Miller and Oli Green have been seen together at public events since 2022, with the relationship maturing alongside busy filming schedules. On the night in London, attention stayed on Sienna Miller’s look while the personal details remained measured. That restraint has defined much of their shared public life.
Age and dates help frame the story. Sienna Miller, born in 1981, marked the Fashion Awards appearance at 41. Oli Green, born in 1996, was 27. Sienna Miller’s daughter, Marlowe, born in 2012, was 11. The British Fashion Council hosted the 2023 ceremony on December 4 in London’s Royal Albert Hall. These are the facts that set the scene and explain why the images carried so far.
So what does the moment add to the larger conversation. It shows how a high profile event can welcome pregnancy without spectacle and without compromise. Sienna Miller leaned into clarity and comfort, and in doing so offered a straightforward template for formal dressing during late trimester stages. The industry watched, took notes, and moved on to the work of the night, but the images keep circulating for a reason.
