Sienna looked like a French style icon in a chic sleeveless cream top featuring pleated detail, which she paired with skinny black cropped trousers. Her accessories were minimal but glamorous – she rocked a pair of a tan suede peep toe boots and carried all her travel essentials in a Saffiano London Tote bag from Kurt Geiger.

When it came to her beauty look, the American Sniper actress could easily have stepped out of old Hollywood. Her blonde locks were swept back into a low bun for a chic yet fuss-free travel look, and she added a slick of statement red lipstick for daytime glamour, completing the look with the ultimate celebrity must-have – oversized sunglasses.

Sienna has been enjoying some downtime in London in recent weeks, supporting fiancé Tom Sturridge who is currently starring in new play American Buffalo at the Wyndham Theatre. The couple have been keeping a relatively low profile since Sienna gave birth to daughter Marlowe two years ago, and have only recently returned to the spotlight.

Despite repeatedly being praised for her effortlessly cool sense of style, Sienna has maintained that fashion is no longer a priority in her life.

“I don’t know what the new fashion trends are!” Sienna admitted to French newspaper Le Figaro. “With my daughter, Marlowe, I don’t have time to follow this anymore.

I love fashion but I’m not obsessed by it. I love work, my style, but I don’t think only about that, even though some people want to believe the contrary. I don’t wake up in the morning saying, ’Hmm, what an icon I am!’”
