Men's blue blazer

A men's blue blazer is the closest thing to a wardrobe default, working over almost any trouser colour without ever reading as the wrong choice for the occasion.

Fabric and shade depth

Cut in 100% wool at a smooth worsted weave for the tailored styles, the range runs from a lighter mid-blue through to a near-black navy, sourced from the same mills that have supplied British tailoring for well over a century. A half-canvas construction lets the jacket move naturally, following the same standard Hackett London has applied since opening its first shop on King's Road in 1983.

Why navy remains the most versatile men's blue blazer

A near-black navy reads formal enough for business meetings while a lighter mid-blue leans more casual, giving the same silhouette genuine range across occasions. This flexibility is exactly why blue has remained the single most consistent colour across Hackett London's tailoring, rather than one option among equals.

Should a blue blazer match trousers exactly?

A blue blazer generally works better against contrasting trousers, such as grey or stone, rather than an identical shade of blue, which can read as a mismatched suit rather than a deliberate combination.

What shirt colours pair with a blue blazer?

White, pale pink and light blue all pair reliably with a navy or mid-blue blazer, with white offering the most versatile, classic contrast.

Is a blue blazer suitable for evening events?

A deep navy blazer works well for smart-casual evening events, though a genuinely formal black-tie occasion calls for a tuxedo rather than a blazer.
