Sienna Miller’s Fairy Princess Pregnancy Hair Is My 2026 Must-Have
Sienna Miller – the woman with the hair that’s inspired a thousand cuts – debuted two things at the 2025 Fashion Awards. First, a sweet baby bump, draped beneath a sheer Givenchy gown, confirming that the star is expecting her third child (her second with Oli Green.) Secondly, a new, crimped hairstyle.
Swapping her usual tousled locks for a hip-tickling mane that looked like it had just been pulled out of two braids, Miller, in our minds, looked like a fairy princess.

An updated version of her signature bedhead hair, her new style ventured further into the boho canon, thanks to a mix of backcombed sections, textured ends and fluffy volume. Adorned with cascading, pearlescent earrings, Miller appeared alongside her husband, as well as Mick Jagger and Charlotte Tilbury. In her words, Miller describes it as “old-school McQueen, romantic, Mother Of Dragons” hair.
On the face, Miller’s monochromatic rose-toned make-up was a hit list of Tilbury’s bestsellers. The lips were painted an antique rose shade, a combination of Lip Cheat in Iconic Nude and Pillow Talk Love Effect Lipstick K.I.S.S.I.N.G in Naughty Talk. On her cheeks, Miller chose the Unreal Blush Healthy Glow Stick in Peachy Glow, while a matching apricot pink washed over her eyelids.
Back to the hair. To mimic Miller’s bohemian vibe, sleep with two or three braids in, and unwind them come the morning. Then, take a texture spray and mist the hair as you run your fingers (or a comb) through it. Don’t worry about being too careful; the entire thing should look a little rumpled. Smooth the top with a brush and hairspray or a clever smoothing stick, gently backcombing any areas that need a little zhuzh. One more spritz of texture spray and you’re good to go, like Sienna Miller.
