4 Holiday Dressing Rules, Straight From Sienna Miller

Admittedly, the fashion industry tends to have an obsession with It girls—the models, actresses, and social media stars who are currently buzzed about. As much as we love to follow along with what’s happening at the moment, few style stars keep that perennial It appeal going quite like Sienna Miller. She could have been dubbed the queen of boho everything in the early aughts, but the 34-year-old actress dressed much more classic, sleek, and tailored when we sat down with her this week. The occasion, of course, was to celebrate her ongoing partnership with Burberry, whose holiday campaign, The Tale of Thomas Burberry (much more like a major motion picture trailer than a straightforward fashion film), she appears in. But with holidays on the brain, we also took the time to tap her expertise on all things party style.

“These days when I go out, I pick my battles,” Miller tells us about her typical approach, citing Edie Sedgwick (naturally) as her ultimate party-girl inspiration. “I don’t go out too often, and when I do I want to have a really good time, and that probably involves some dancing. In which case, I would try to wear a high heel that has like a platform and won’t murder my feet. And also around the holidays, I get swept up in the festive things. I quite like sequins, and Christmas is the one time of the year where you can go for a little bit of the sparkly front, which I don’t normally do.”

To further distill Miller’s innate cool-girl style, serious fashion know-how, and more-is-sometimes-more attitude to festive-wear, we asked her to walk us through some of our favorite party looks she’s worn and give us the tips behind them so we can master for ourselves.

Read on for four key rules that Miller swears by.
