We get it: Saturdays are for kicking back, but that doesn't mean you have to let your styling edge fall by the wayside. In fact, there's an easy solution to tomorrow's off-duty look, and it has everything to do with Olivia Wilde. The actress stepped out for the Anna Karenina premiere in NYC in a wintry mix of polished layers. Sure, there's a little bit of a prepster feel, too, but even nontraditional stylers would do well by a quick pop of plaid. Here's the quick breakdown (so you can assemble a similarly chic outfit and head to brunch with minimal effort). Style a tartan-printed blouse with your coziest knitted sweater — cable-knit, fisherman, cashmere, angora, it all works. Add your favorite pair of skinny jeans and ankle-cut boots; the slim-meets-no-frills silhouette on bottom will help to even out the chunkier layers on top. Then, focus your attention on the final outerwear touches à la Olivia. Her sleek black coat and ribbed gray scarf provide the functionality of a great cold-weather ensemble and keep the cool, classic vibe intact. Got all that? Now, shop the pieces below to complete your Saturday transformation. You can thank us (and Olivia) later.Clockwise from top left: Topshop Boutique Angora Stitch Jumper ($130), J.Crew Perfect Shirt in Tartan ($78), Mango Super Slim Jeans ($70), Ecote Eliana Double Zip Ankle Boot ($69), Acne River Angora Ribbed Scarf ($194), Proenza Schouler Wool-Blend Coat ($2,250).
