I have long been an admirer of Sienna Miller‘s effortless style, and it seems that this won’t be changing any time soon. After a whirlwind trip to Cannes Film Festival where the actor stole our attention in a boho-inspired Chloé gown, she’s once again become a talking point in the Who What Wear office, this time for her elevated take on off-duty style.

Stepping out in London this week, Miller crafted a polished ensemble that’s just become my template for easy weekday elegance. To contrast the formal feel of a gray blazer, she styled it with the sleeves casually scrunched up to her elbow, showing some skin and relaxing the smart piece. Leaning further towards the casual side, she selected a pair of billowing barrel-leg jeans to add volume to her look, along with a suede bag from Jimmy Choo to accessorize.

Finessing her outfit with some polished additions, Miller layered on two gold chain necklaces and selected a pair of pointed-toe boots to add an angular element to the baggy shape of her jeans and bag. Inspired by Miller’s styling choices, I’m eager to emulate this look at home, and luckily for me, my wardrobe already contains all of the wardrobe essentials that make up the chic, celebrity-approved outfit.
