The British Fashion Awards 2025, held at London's iconic Royal Albert Hall, was a night of high glamour and stunning style. Among the constellation of stars, one shone with a particularly radiant light: actress Sienna Miller, who chose the prestigious event to announce her pregnancy.
The Star-Studded Reveal and Flawless Complexion
On Monday, December 2, 2025, Sienna Miller captivated onlookers in a breathtaking white sheer gown by Givenchy. While the joyous news of her pregnancy was the headline, beauty enthusiasts were instantly drawn to her impeccable, luminous complexion. The 43-year-old actress collaborated directly with makeup icon Charlotte Tilbury and her expert team to craft the stunning look.
The standout product responsible for her signature glow was the Charlotte Tilbury Unreal Skin Sheer Glow Tint Hydrating Foundation Stick. This vegan and cruelty-free stick foundation is celebrated for its lightweight, buildable formula that provides a sheer-to-light coverage with a natural, radiant finish.
Breaking Down the Award-Winning Makeup Bag
Priced at around £35, the foundation stick was a savvy beauty buy during the brand's Black Friday sale, available for just £26.25. Its skincare-infused formula contains hyaluronic acid for deep hydration, Vitamin E for antioxidant protection, and Collageneer™ to promote skin firmness. Daikon Radish Seed Oil works to smooth and nourish, making it a true hybrid product.
The application is famously fuss-free—a simple swipe and blend is all it takes to achieve that coveted natural glow. To perfect Sienna's base, the makeup team began with the Charlotte Tilbury Invisible UV Poreless Primer, which primes, hydrates, and protects the skin. This product was also on sale, reduced to £30 from £40.
For the final touches, Charlotte’s Airbrush Flawless Finish Powder was used to mattify specific areas and enhance the pore-blurring effect. The look was completed with a swipe of the Pillow Talk Love Effect Lipstick in the shade Naughty Talk, a colour valued at £21.75, down from its usual £29 price tag.
How to Achieve the Look for Less
For those inspired to recreate Sienna Miller's red carpet radiance, the key product—the Unreal Skin Foundation Stick—remains available at a discounted price, offering a luxurious finish for under £30. The coordinated use of primer, powder, and lipstick from the same brand demonstrates the power of a curated makeup routine to create a cohesive and camera-ready appearance.
Huge congratulations are in order for Sienna Miller on her pregnancy news, and also for showcasing one of the most talked-about beauty looks of the night, masterfully created by Charlotte Tilbury.
