Instant Style: 9 Looks Perfect for Your Weekend Activities

With the changing of the leaves comes a whole host of cozy activities just as picture-perfect. So get in the frame, and dress accordingly.

Occasion: Girls' Brunch

Why It Works: This elevated play on loungewear will get you noticed but still out the door in 10 minutes. The upgrades: Layer an oxford shirt under a quilted sweatshirt for preppy polish, and skip sneakers in favor of brogues to sharpen casual knit pants. Oversize shades and a baseball cap mean minimal hair and makeup time (and more sleep!).

Occasion: Tailgating

Prepare for the big game in colorful layers so you'll be toasty and scoring plenty of style points. (Stick to face paint in the same color scheme.)

Why It Works: Everything about this bright blue quilted jacket says, "Go team!" Keep the sporty spirit popping with a varsity-like striped scarf, but in a sophisticated palette like ocher and gray. Bonus: It can double as a shawl.

Why It Works: Love sports but don't do parking-lot couture? A crewneck and miniskirt combo is cute but laid- back when tempered with high-tops. Sneak in an extra print (and make new friends) courtesy of a rolled-up blanket.

Occasion: Holiday Dinner

Match your outfit to the menu: Nothing says Thanksgiving like a rich assortment of fall hues, such as warm squash and deep wine.

Why It Works: For a more formal gathering, fluid silhouettes—like this season's robe coat over a silky blouse and a midiskirt—offer easy elegance (and room for seconds). A structured tote and pointy-toe pumps amp up the polish.

Why It Works: Let slouchy trousers in graphic black-and-white do the talking and keep the rest of the outfit simple. Add some tonal warmth with a burgundy sweater, then relax about spilling any of that merlot.

Occasion: Apple Picking

Why It Works: Want your pick of the bunch? Durable denim was made for climbing, and yellow galoshes will let them know you mean business. Bring a charming wicker tote to hold your spoils—all the better if it matches your topper.

Why It Works: A long skirt coupled with ankle boots will (stylishly) protect your legs while you're strolling in the grass. Go heavy on the knits—a chunky cardi over a thick sweater never fails—in case you decide to stay for a hayride at dusk.

Occasion: Date Night

Why It Works: Give a nuzzle-worthy turtleneck and kicky ombré jacket some edge with provocative leather. A tasseled cross-body and suede Chelsea boots lend a cheeky touch—perfect for catching that fright-night blockbuster.

Why It Works: Cider cocktails on the agenda? Dare to be sleeveless with a little help from a tailored white coat. Drape it over the back of your chair to reveal a girlie LBD, updated in a fiercely feminine floral brocade.
