Sienna Miller Is Our New Off-Duty Style Guru
The "Sienna-ssance," as we like to call it, started about this time last year. Following a knockout turn in Miu Miu at the Golden Globes in 2015, Sienna Miller, in conjunction with her über-styist Kate Young, began to rewrite the fashion history books by fully shaking off her original bohemian image and crafting a new, exciting sartorial path.
It's one that has since been tinged with a pared-back confidence (aided by lots of Céline and Gucci) by day and more adventurous catwalk choices by night—she wowed in gown after gown throughout Cannes 2015 (where she was a judge on the event's panel), and we're hoping for more of the same when the film festival kicks off next month.
In the past few weeks, a couple of off-duty Miller-branded ensembles have really inspired us to rethink our day-to-day outfits. Her ratio of minimal to maximal is the perfect balance of understated, only with excellent flashes of personality. Go through the gallery to see how the style icon is doing casual now and shop from her looks…
