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.

OK, so first of all — it’s Valentine’s Day! I hope you’re spending the day just as you’d like, and in style. To that end —  if you’re looking to shore up or switch up your casual winter style  after a few months of bone-chilling cold, this week’s #OOTD will sort that out nicely for you. We talked last month about how to wear a turtleneck this winter, but we’re going a bit more accessible and a bit more versatile today — as you’ll see below. It’s taking pieces that you might already have in your wardrobe, or pieces that you might be coveting — ahem, the Taylor Stitch Maritime Submariner Jacket — and putting in all together in a look that you can wear any day of the week. So, Sunday brunch? Check. Heck, Saturday brunch? You got it. And a weekend coffee date or a business casual day at the office? Absolutely. For more daily style inspiration, follow your Style Guide author on Instagram. Join us later this week for our regularly scheduled #menswear programming, too. Happy shopping!

Taking classic pieces and upgrading the fabrics and fits.

The Jacket: Taylor Stitch Maritime Submariner Jacket, $248 — Ahh, yes. The warm, comfortable, slim-fitting and versatile Taylor Stitch Maritime Submariner Jacket. How could you not love it? Right? Right.

The Sweater: Bonobos Merino V-Neck Sweater, $58 — If you’re going to wear something more simple in form — like a V-neck sweater — you might as well make yours a high-quality, well-fitting piece in a rich winter color. Wondering how it should fit?  Read my recent Effortless Gent piece on how to find the perfect sweater (nudge, nudge).

The Oxford: JackThreads The Oxford Shirt, $39 — Is there a more classic combination for versatile, casual style than a V-neck sweater and an Oxford? Not quite — especially when it’s a great deal from the folks at JackThreads.

The Denim: Buck Mason Lou Slim Fit Jean, $175 — If you haven’t checked out Buck Mason, I’d advise you do so — from the brand’s classic short-sleeve chambray shirts to slim denim like this pair (faded just right), it’s tough gear for the modern man.

With versatility and great comfort & fit in mind, dressing in casual style can be easy and hey, fun. And if you’ve been looking for ways to switch up your style this winter, a great V-neck and Oxford is one way to go. These are pieces you might already have, but you can amp things up with something like the handsome, rugged Maritime Submariner Jacket and slick footwear like the Astorflex Bitflex Chelsea Boots. Oh, and if adding to your watch collection is a priority in terms of your 2017 style resolutions, there’s no better place to start than the very investment-worthy Ace Automatic Watch.
