Editor’s note: You’ve surely seen this hashtag lots of different places, including on Instagram. But how does that carry over to real life? The #OOTD series will take one great item and put together a versatile, stylish outfit around it. Look for past features here.

Every once in a while, you just want to mix up your style — right? Maybe if you’re a guy who frequently suits up , you feel compelled to dress down off-duty. Even if you find yourself dressing in business casual style for the office — rather than a suit — it still pays to have a few go-to, off-the-clock looks on-hand. And when you throw in the dual challenges of navigating winter weather while looking sharp, it adds another piece to the puzzle. That’s what we’re tackling today — we’ll get a bit out of the box in terms of classic winter style and go just a tad more casual and a tad more rugged. The basic building blocks of a crisp winter ensemble are still there — starting with classic dark denim and tough leather boots — but the way in which the outfit builds from the ground up will hopefully get you thinking about ways to refresh your style this year. Intrigued yet? Check out the full #OOTD below, and join us on Instagram and Facebook for more #menswear content, 24/7.

The Cardigan: Iron & Resin Fletcher Cardigan,$110.98 — Here at the dear old Style Guide, we sure do love a shawl-collar cardigan. And seeing as this one is available via Huckberry in a warm cotton-fleece blend, it’s worth the buy. You could always add a crisp, functional Outerknown parka if you need an extra layer.

The Henley: Bonobos Slub Jersey Henley in Off-White Microstripe, $55 — Shawl-collar cardigan? Check. Rugged henley? Check. It’s as classic and comfortable of a winter style combo as it gets.

The Scarf: S.N.S Herning Torso Scarf, $96.60 — Nearly a hundred bucks is a lot to drop on a scarf — but when it provides significant warmth and style to rival that of the revered Daniel Craig in “The Girl with the Dragon Tattoo,” it’s worth doing.

The Denim: Nudie Jeans Grim Tim Denim, $124.98 —  Whether you consider yourself a rock star or not, there’s something to be said for owning a slick, slim pair of black denim. The Grim Tim is that pair — and they’re a nice way to switch it up from dark indigo selvedge, too.

The Boots: G.H. Bass Buxton Boots, $425 — We talk a lot about investment-worthy purchases that convey great style and timeless appeal — the G.H. Bass Buxton Boots are one such purchase, and they add a bit of a unique contrast to the black denim.

The Socks: Wigwam Merino Lite Hiker Socks, $12.98 — Sometimes, you just need comfortable, functional socks that fight the chill — if that’s the case, pick up a couple pairs of these Merino Lite Hiker Socks.

The Watch: Standard Issue Instruments Pilot Mission Timer, $199.98 — Yet another standout piece of gear sold by Huckberry, the Pilot Mission Timer is tough, practical and rugged. Don’t worry about the black strap-brown boots color combo — it works in this casual ensemble.

The Hat: Columbiaknit Watch Cap, $17 — Just like the Merino Lite Hiker Socks, functionality and warmth is sometimes the name of the game. This cap is more than fairly priced, too.

The Gloves: Hestra Granvik Gloves, $180 — They might not be pictured in the above grid, but that doesn’t mean you don’t need reliable, tough winter gloves — Hestra is the place to go in this case.

Alright, let’s bundle up and get out there this winter. When you start with well-fitting basics — like a slub jersey henley — and add a tough-yet-comfortable Iron & Resin shawl-collar cardigan, you’ve got the foundation of a warm winter outfit.  In fact, it’s this very outfit that I frequently find myself wearing when it’s chilly. At any rate, slim black denim and rough-and-tumble leather boots are essentials in any season, especially cold weather, and the overlooked details — like warm winter socks and a nice winter hat — are just as critical to keep in mind before you step outside. And if it’s a new watch you need, something as functional and dependable as the  Pilot Mission Timer should get you where you’re going with plenty of time to spare.
