Men's Blazer Jackets

Blazer Jackets for Men - Smart Casual to Formal

A blazer jacket sits in the sweet spot between a full suit and casual wear — more structured than a sports jacket, more relaxed than a suit jacket. Whether you need a smart blazer for the office, a formal blazer for a wedding or event, or something with more personality like a checked tweed or velvet style — our collection of 134 mens blazer jackets covers every occasion and colour.

Slim Fit & Tailored Fit Men's Blazers

Fit is everything with a blazer jacket. A mens slim fit blazer jacket sits close to the body — sharp, modern, and works particularly well for smarter occasions and evenings out. A tailored fit gives you the same structured look with slightly more room through the chest and shoulders — the more versatile option if you're wearing it across different occasions.

Formal Blazers for Men

A formal blazer for men works where a full suit feels like too much — weddings where you're not the groom, smart evening events, business meetings with a dress code. Double breasted styles in navy or black are the most formal option. Single breasted in grey, beige or check gives you more flexibility between formal and smart casual.

Men's Blazer Jackets by Colour

Not sure which colour to go for? Navy blazers are the most versatile — work with virtually any trouser colour and suit any occasion. Blue blazers offer a slightly lighter, more relaxed alternative to navy. Beige blazer jackets are the go-to for summer weddings and smart casual events. And brown blazers — particularly in tweed or herringbone — bring warmth and character that navy simply can't match.

How to Wear a Men's Blazer Jacket

Pair with chinos or dark trousers for a smart casual look — no tie needed. For a more formal occasion, add a tie or pocket square and match your trousers to the blazer fabric. A checked or tweed blazer works particularly well with plain dark trousers — let the jacket do the work and keep everything else simple.
