The red colorway offers a classic style when it comes to the flannel shirt. It’s typically the go-to primary color when we think of a plaid flannel shirt.

To get the best results when pairing a red flannel shirt with bottoms is to opt for dark jeans and a black t-shirt.

Next, you’ll want to toss on a sleek pair of sneakers like this one we highlighted in our past article (click here to read).

If the venue you’re attending requires a more elevated attired, then we highly suggest pairing the ensemble with black or tan chelsea boots to keep things looking stylish and classic.

Black Flannel

Next, let’s talk about the black flannel shirt outfit.

Imagine you have to go meet someone for a date in SOHO and you want to look edgy yet still refined. This is when we’d opt for the black flannel.

There are two ways to really wear this flannel or any flannel in this case.

You can totally wear an unbuttoned flannel shirt. We’d recommend sporting a cool necklace to give your neckline some subtle visual interest.

If you feel better with an undershirt, this is NOT the time to bust out a stretched-out Hanes shirt you’ve had tucked away in the corner.

Instead, you’ll want to wear a great-fitting plain t-shirt. We really enjoy a sleek black men’s t-shirt although you can interchange this with a white shirt if that’s more your thing.

One of our favorite ways to further elevate this outfit would be to wear a black leather jacket.

Boom, you’re now a rockstar.

Green Flannel Shirts

Lastly, we’ll touch on the green flannel shirt.

For us, it’s definitely not at the top of the list, but if green is more your style, we don’t judge.

Remember how we said most men probably don’t want the lumberjack look? Well, for those of us that do, the basic green flannel shirt is going to be your best bet.

Let’s say you have a big beard and want a rugged outdoorsy style, then a green color flannel shirt might be for you.

However, we like things that are a bit different, so we totally dig this olive green flannel shirt from RSVLTS. As you can see, we’re obsessed with them right now.

We recommend pairing your green shirt with your favorite graphic tee and of course a pair of jeans like your darker blue or grey jeans. If you want to give it a more street casual look, we opt for a really fun graphic tee too.

Now that we have some of the basics out of the way, we can get into the various flannel shirt outfits that you can easily create at home.

First, let’s touch on the casual flannel look.

Suppose we have to head to outdoor activity, brewery, or brunch. We would most likely want to wear something a bit more casual. To achieve this look, we’d recommend wearing your flannel with your favorite pair of jeans. Let’s opt for a red flannel shirt and blue jeans.

Blue denim jeans just help give off a more casual aesthetic, but the colored flannel shirt will help keep things looking slightly elevated versus a basic t-shirt.

If you really want to amp up the casual look we suggest wearing a cool graphic tee to help complete the look and a sweet pair of kicks like this ensemble shown in the image above.

The Smart Casual Look: flannel shirt outfits for men

Looking to build a more elevated look?

This is where you’d want to create a smart-casual look. We’d recommend the black flannel with black jeans. Keep it simple stupid.

If you’re grabbing drinks, let’s make you a bit more sexy by leaving the top couple of buttons unbuttoned.

Boom you little sex kitten you.

Answers to Frequently Asked Questions About What to Wear Under a Flannel

Learning what to wear under a flannel truly depends on each of our unique style choices. That being said, we’ve found some of the most common questions when it comes to styling your flannel shirt outfit.

Do you wear anything under a flannel?

Yes, typically a basic high-quality cotton t-shirt will do just the trick. If you want to achieve a minimal look then stick to solid-colored shirts underneath. If you want a more rockstar look pair your flannel with a cool graphic t underneath.

What do you wear under a flannel jacket?

When it comes to styling your flannel jacket you want to think in terms of layers. Most men typically get hot so layers are key to maintaining comfort. We suggest keeping things minimal for easy closet rotation. Pair with a crisp t-shirt, dark-colored jeans and light-colored kicks to make things pop.

How do you properly wear a flannel?

You want to keep things sharp looking to really make an outfit pop. So, keep your flannels modern versus crazy. Keep your undershirt crips and new. Keep pants dark and shoes brighter.

What do you wear under a flannel in the winter?

During the colder months, we love wearing a hoodie underneath our flannel shirts.

A great option is to think about wearing extra layers that you can pair down into.

Wear your hoodie (this would be the middle layer) with a comfy cotton t-shirt underneath. Throw on your flannel and then jacket. This helps keep you warm, however, if you do get hot you can easily tie your flannel shirt around your waist for a cool grunge look.

Should flannel be buttoned or unbuttoned?

The answer comes down to the formality of the event you’re attending. If you’re hanging out with buds at a local bar or going over to a friend’s house to play games, you can opt to keep it open and casual.

For a formal events like an evening out or going to a nightclub, we recommend buttoning that bad boy up. Although we wouldn’t consider it to be a proper button-down shirt, it can pass if it’s minimal.

We we think the best way to wear a flannel is opened up.

Is it OK to tuck in a flannel?

This depends on the entire ensemble you’re wearing. In particularly, the outer layers.

For example, if you’re going to wear a leather jacket, then tucking your shirt in is proper. Or perhaps you’re going to wear a sweater over your flannel. Then tucking your shirt in would do.

Do people wear hoodies under flannels?

Absolutely! Especially if it’s cold weather season.

This is such a great look that elevates your style game. Start with wearing a base layer of a solid cotton t-shirt, layer with a hoodie, and top off with your flannel. You’ll look like a solid style icon in no time.
