How to Wear a Blazer

Before we delve into the realm of what trousers, shoes and accessories to wear to create the perfect smart casual look, we must first discuss the casual blazer itself. There are so many different styles out there to choose from, it can sometimes be difficult to differentiate between what is a blazer, a sports coat or a suit jacket. Luckily we're here to help you figure out the differences.

What to Wear With a Blazer

The blazer is considered to be less formal than the suit jacket but more formal than a sports coat, and casual blazer outfits are easy to get your head around. One of the key differences with a suit jacket is that it's not made with a matching pair of trousers and less structured in the shoulder area. The most common variety is in navy and for men in the British Navy, it was considered the jacket of choice in the early nineteenth century, when the garment first became hugely popular. They've progressed since then and a greater variety of colours, such as black, grey, dark red, and bottle green, are now widely available. It's perhaps the material that differentiates this piece to the sports coat and suit jacket, rather than colour, with most men's blazers being made from worsted wool, serge, cashmere, polyester, fresco and hopsack. They also mainly come with a single-breasted fastening. casual blazers for men street style toppicks

Sport Coat

A sports coat or sports jacket is more casual than a blazer and will come in a wide range of colours, usually in lighter shades. They will be patterned with anything from stripes to plaid to houndstooth. The sports coat comes in a wider variety of materials such as corduroy, flannel, tweed, or herringbone. The sports coat can definitely feel a little more preppy, especially if accompanied with a pair of chinos and loafers. A sports coat with jeans is another classic combination that men tend to go for. It will often come adorned with added extras such as elbow patches, ticket pockets and will have a patch or hacking pockets to fall in line with its sports heritage (this jacket was traditionally worn for sporting activities such as hunting or shooting). The fit of a sports jacket is not as structured as a suit jacket or blazer and generally, comes with a looser fit to allow for warmer layers to be worn underneath. Again,  a 2-button single-breasted fastening is most common. green sport coat for men wearwith

Suit Jacket

Finally, the suit jacket is the most formal option and is defined as such by usually being accompanied with a matching pair of trousers. Suit jackets will nearly always come in more subdued charcoal greys, blacks, and navy and can sometimes, but not often, feature subtle patterns such as stripes and checks. The suit jacket will be void of the extra details that you would find in a sports jacket in its bid to look sharper and more sophisticated. The fit of a suit jacket is made to be slimmer than a blazer to create a more refined silhouette because suit jackets are not designed to accommodate multiple layers underneath. The formality of this type of jacket means that it can be slightly more difficult to style casually but, if wanting to get a little bit more everyday use of it, don’t be afraid to team your suit jacket with jeans. The only issue that you may have is having to wash the suit jacket more than its counterpart trousers resulting in a difference of colour developing between the two. casual navy blazer mens street style shopthelook

How to Wear a Blazer and Jeans

It allows you to heighten any outfit and add detail and texture to a look.Black and white are a perfect combination and should always be the go-to choice when choosing black blazer outfits. The blazer and jeans look is a classic so you can be quite confident you'll look good. Choose a slim-fit black sports coat or blazer and pair with some skinny fit jeans and a plain white T-Shirt.

The Fit of a Blazer

The Fit is everything when it comes to your blazer, and because there are so many blazer styles out there, it can be tricky to pin down. It's completely pointless spending all your hard-earned dollar on something that resembles a bin bag and doesn’t fit the contours of your body. The key is to avoid your blazer looking too big or too small, watch out for these tell-tale signs that the fit may be incorrect. mens correct fit blazer

Too Tight:

  • There will be an ‘X’ shape forming at the closure where it is pulled too tight across your chest
  • The seam where your shoulder pad meets the arm will not meet at the correct place which will cause straining
  • If the shoulders are not wide enough this may cause the length of the arm to ride up and become too short
  • The collar of the blazer will bunch and pull at the neck, limiting movement and putting the whole fit off kilter
  • If the blazer is too short it will ride up the wearer’s back and fully expose the seat

Too Loose:

  • The blazer closure will sag and droop forward
  • The shoulders extend past your actual shoulders creating a lumpy and untidy silhouette
  • The length of the arms falls way past the base of your thumb making it look like you’ve swiped the blazer from your Dad’s wardrobe
  • The collar will pull away from your neck leaving a gaping hole between yourself and the blazer
  • If the blazer is too long it will drown the wearer and come past the seat

Best Blazers For Men

This can depend on a variety of factors, ranging from the season, your personal taste and what kind of social situation you find yourself in. Take a look at a few different fabrics that you could consider for your next favourite blazer.


Perfect for the colder months, tweed is a practical and durable heavyweight fabric which will keep you warm and still look stylish when the winter season is upon us. Tweed will add an interesting element of texture to an outfit and definitely should not be confined to elder gents in country manors, as is often its perception. Tweed can definitely be modernised to suit contemporary trends and should not only be seen as a formal option. Depending on the strictness of your workplace, tweed can be a great casual blazer for work if teamed with a roll neck or open neck oxford shirt. The versatility of tweed speaks for itself as it can be worn with a multitude of looks and colours. A grey tweed blazer will work perfectly with a pair of dark grey, or even black trousers teamed with a crisp white shirt underneath. mens green tweed jacket street style wearwith


Similar to tweed, wool and flannel blazers are often considered best in the autumn and winter season, lightweight flannel in the 9-11 oz range can be a great option in the warmer months too. Wearing wool in the winter will keep you warm, but you still want to stand out from the crowd. Try wearing a coloured wool blazer with a classic look underneath to really make a statement. green wool blazer for men wearwith
