Black Blazer Outfits

The most common (or clean-cut) way to wear jeans with a blazer is opting for the classic black slim or skinny jean. A look which can take you from your day at work to the pub, it’s a combination which doesn’t have to break the bank. For us, choosing a black jean provides you with all the choice in the world for what colour shirt and blazer you decide to go for, let alone fabrics. Coincidentally, this means you don’t have to feel restricted when experimenting with different textures and colours with your outfit.

Blue Jeans with Blazer

Blue jeans with a blazer will always be a classic choice when your dress code is smart-casual. Think of it as the best both of worlds; denim is rough and raw while the blazer is your structured and defined. Also just as easy to pair with literally any blazer of choice (apart from Navy, no doubling up here), this smart-casual combination is sure to save you in the morning rush.

Grey Jeans with Blazer

If black and blue aren’t doing wonders, then opt for the light wash of grey denim. Perfect for more winter and autumn seasons, grey denim can be just as easy to wear with your blazer. Our Editors prefer to pair our grey denim with black, navy or printed blazers rather, as opposed to grey. As co-ordination can work for some looks, grey denim on grey blazer really doesn’t, and can leave you looking like you’ve stepped out of a 1940’s film.

Men’s Coloured Blazers

There’s no need to stick to black and grey if colour is more your thing, and a bright blazer can really bring your outfit to new levels. For summer you could go for light pastel colours, like a blue or pink, and for the winter months experiment with patterns and darker shades. Giving your look a bit of personality is the perfect way to make a statement, especially with a classic look.

When opting for colour always remember to keep your jeans simple. This means no stone washes, rips, or extravagant stitching. Opting for too much detail can create a bit of a clash or a headache for eyes. So for this time, take into account less is more.

Coloured Blazers Outfits

To keep things simple you can stick to a neutral pair of blue jeans, and match your blazer with a simple white shirt. However, if your blazer is in a bright or light colour you can achieve a summery vibe by pairing it with straight leg or skinny white jeans. Because of the standout look of a coloured blazer, it’s best to keep the rest of your outfit fairly neutral and simple, or at least in the same tone so there’s not a huge amount of contrast.

Don’t limit yourself by adding character to your look with just colour. If you decide to opt for a bit of print then pair your blazer with classic black jean. It’s the best colour to compliment most prints, as black lowers the attention that can be drawn to your blazer, let alone level out the tones in your outfit. Additionally, with the perks of looking suave with black denim, this is look is easy to transition from season to season.

Men’s Casual Blazer Outfits For Inspiration

Okay, so as the blazer is generally a formal looking piece, when we say casual we don’t mean something you can lounge around in. It simply means dressing comfortably, while still looking sharp. Below are some of the best examples of David Gandy and David Beckham pulling off the casual look with their blazer and jean combination.

Jeans to Wear with Blazers

So there are various ways you can match your jeans with blazers. The general idea is that you buy a blazer and then work out the jeans to pair with it from there. But you might have a favourite pair of jeans in a colour or shade you love, and feel like matching a blazer with them rather than the other way around. If this is the case you need to roughly know what blazers will best suit your jeans in terms of colour and print.

Can you Wear a Suit Jacket with Jeans?

It’s a question that has a two distinct answers, with a lot of people feeling pretty strongly either side. People who answer no usually aren’t too happy about pairing a blazer with jeans either, and people who answer yes are usually more relaxed about the ‘rules’ of fashion. In reality, the difference between a suit jacket and a blazer are fairly small, with the suit jacket always having a matching pair of trousers made to go with it. They’re also a little slimmer fit than the blazer, and can come in sleeker shiner materials.

To pull off a suit jacket with jeans it’s best to keep your jeans slim or skinny fit and avoid a straight leg jean or anything that’s too loose. A suit jacket is a slim fit item so you need to keep the look consistent, and not pair it with anything that’s going to contrast with it too much.

What to Wear With Light Blue Jeans

If you’ve got a pair of light blue jeans then you’ve got a few options to play around with. When opting for the softer blues, stick to lighter colours like cream, grey or pastel blues and pinks when picking your blazer. If you’re going for a bold colour stay away from patterns so as not to go overboard.


What Goes with Dark Blue Jeans

Dark jeans are a little easier to pair with blazers, especially when opting for more neutral tones. Additionally, darker jeans create more of a defined look, making it an easy go-to when the transition from day to night.


Finishing Touches

The more obvious way to customise is adding in some accessories. Watches, sunglasses, chains, and pocket squares all guaranteed to spruce up any look (not all at once, though). However, If you’re unsure of what to add to your look, maybe stick with something simple such as an all gold or leather watch. Lastly, don’t forget to smell great.

How a Blazer Should Fit

    • The sleeves should always fall just above the hand and be slim fitted around the arms.
    • Blazers should be tapered into the waist, but unless you’re super slim avoid the skinny fit.
    • The length of your blazer should be no longer a couple of inches below the hip bone.
    • Make sure your collar is fitted correctly. If you’re wearing a shirt then your jacket collar should rest against your shirt collar.
    • Your blazer should fit closely, but not so tight that you get an X mark across your chest.

Blazer Styles

Before we have a look at the best blazer and jeans combinations, it’s always good to refresh our memory on the different styles of this iconic piece of menswear. Apart from the general fit guidelines outlined above, another essential factor to consider is the construction of your blazer. This obviously informs the way the garment will fit and it’s important to choose the cut that best suits your body type.
