The dress code at Mary-Kate and Ashley Olsen [1]'s office can best be summed up in just two words: business chic. The two were spotted not far from their NYC offices, showing off their coordinating business-casual looks. Each styled a sharp play on menswear — Ashley reached for a cape to top her button-down and skinny black pants, while Mary-Kate outfitted her take with a double-breasted coat and wide-leg trousers. And though both relied on the same classic palette and essential pieces, their coordinating looks are hardly the matchy-matchy outfits some of us were forced to wear with our siblings. In short, this just might be the grown-up way to channel the same vibe, without actually stealing your bestie's look. Read on to see how the sister design duo [2] styled their respective looks, then shop the key pieces.
