Right on par with just about every other jeans and sweater combo she's worn, Katie Holmes nailed the classic off-duty look by styling only the necessary basics. Translation: she handed us (and you) a chic Fall ensemble with an easy-to-emulate twist just in time for the weekend. And the best part? You won't even have to dig too deep within your wardrobe to follow suit. Style a crisp, collared button-up shirt under a cozy, oversize neutral-toned sweater. Then, pair the top layers with a flared-jean silhouette. The denim choice here is really up to you, but we have to say, Katie's wide-leg pant shape gave the whole look a more casual, relaxed vibe. To finish, she wore Derek Lam's awesome maroon-hued camera bag like a crossbody style. You may remember our own ode to its greatness here. While you don't have to break the bank on the bag front, the key is to offset the laid-back pieces and soft palette with a slicker, punchier statement. So, now that you've got the Katie Holmes-meets-Saturday style breakdown, shop away.
