The Rare Work-Friendly Matching Set, Spotted On Sienna Miller

Ever since the great Matching Set Revolution of 2014 (championed by one Taylor Swift), we've managed to coordinate our separates for almost every environment and situation. We've seen the baseline summer trend transition into the colder months, adopted by a wide range of celebrities for everything from late-night appearances to dressier dates. But, there's one scenario we haven't cracked: the workplace. Often too casual or too revealing, matching sets aren't an ideal silhouette for your 9-to-5 — especially if there's a more buttoned-up dress code. Sienna Miller, however, is breaking the barrier, moving us a tad closer to upping our matchy-matchy office-wear game.   Miller took a break from her jam-packed festival schedule to stroll around Cannes yesterday, donning a sophisticated ensemble in what seems to be a favorite color. The sleeveless top and wrap bottom look put-together, with only an itsy bit of skin showing around her torso in the gap between her cropped blouse and high-waisted skirt. Swap the buckled sandals for covered-toe heels or flats and put a crisp blazer on top, and this ensemble can finally join your on- and off-duty wardrobes in sartorial matrimony. Or, when paired with a leather moto jacket, it gives your brunch go-to a just-got-off-the-plane-from-Cannes refresher. See how you can copy Sienna's look for your own weekend wear, below.
