Just because the calendar says autumn is officially upon us, that doesn’t mean you should break out your wool coat and tall boots. This time of year the weather can be fickle, to say the least, bouncing from blistering to bitter and often hovering in that confusing transitional zone. That’s why jackets are a key component of any fall wardrobe.

The right lightweight topper can be just the finishing touch your outfit needs and let you get into the art of layering—without adding bulk or causing you to overheat. So, we’ve rounded up six fall options, from denim to leather to tweed, that are guaranteed to get you through the cooler, in-between season in style.

Trail Blazer

A.L.C. Sedgwick Jacket, $595; intermixonline.com

Your closet should be stocked with at least one oversize structured blazer this fall, preferably of the checked, double-breasted, menswear-inspired variety. An ideal option for when the weather doesn’t quite call for a proper coat, this piece also instantly dresses up any outfit. Try it with a T-shirt and jeans and you’ll see what we mean.

Red Leather Day

7 For all Mankind Leather Biker Jacket, $799; nordstrom.com

The great thing about investing in a luxe leather jacket is that it only gets better with age—the more you wear it, the more comfortable it gets. Plus, the broken-in leather will provide that perfect lived-in look. If a classic black moto feels too biker for you, opt for a supple style in a rich hue like Bordeaux. You’ll still get the cool vibe but with a sophisticated twist that looks more polished than punk.

In the Trenches

The trench has evolved over the years into more than just a preppy requisite for the business-suit-and-briefcase crowd. These days, you can find all sorts of modern and stylish takes on the wardrobe staple. That includes this contrast-lapel interpretation that feels more forward than dated—but still maintains the refined look of its classic heritage.

The Need for Tweed

Zara Textured Weave Blazer with Trim, $100; zara.com

A Chanel-esque, boxy woven jacket is another chic outerwear alternative—one that’s extremely versatile. Wear this timeless piece as a ladylike layer over a sheath dress or mix things up with a pleated skirt and heels. To elevate your casual look, throw it on with denim and ankle boots. However it’s styled, you’ve got a wardrobe winner.

It’s a Cinch

& Other Stories Belted Denim Jacket, $119; stories.com

The jean jacket has gotten a welcome upgrade thanks to one of the season’s most coveted silhouettes: the belted jacket. A hybrid of ’70s, safari, and military, tie-waist outerwear is a fall must-have. In denim, this casually cool style is a great substitute for the classic trucker we all know and love.

Bombers Away

P.E Nation Streamline Jacket, $181; farfetch.com

Give your look a sporty spin with a military-inspired bomber. Tailored and feminine, a cinched-waist juxtaposes the more rugged army elements. The result: a laid-back jacket that’s sophisticated, not sloppy. Layer it over everything from a striped top and slim jeans to a floral-print dress.

Your jacket sets the tone for your entire look—and with one of these stylish, lightweight options, your fall fashion game will be on point.
