Choosing the Right Boys Blazer
When choosing a boys blazer, consider his age, the occasion, season and how formal the finished outfit needs to be.
Linen and lighter-coloured blazers are well suited to spring and summer, while tweed, check and velvet jackets provide more texture for autumn, winter and evening events.
For weddings and formal celebrations, pair a blazer with a crisp shirt, tailored trousers and smart shoes. For a more relaxed smart-casual look, wear it with chinos, loafers and an open-collar shirt.
Boys Blazers from Toddlers to Teenagers
The collection includes boys blazers across toddler, junior and teenage sizes, making it possible to create smart outfits for younger children through to boys aged 16.
For toddlers and younger boys, prioritise a comfortable fit that allows easy movement through the shoulders and arms. For older boys and teenagers, slimmer and more structured blazer styles can provide a sharper, more grown-up silhouette.

Boys Blazer vs Suit Jacket: What’s the Difference?
A boys blazer is generally designed to be worn as a separate jacket and can be combined with different trousers, shirts and shoes. This makes it a flexible option for weddings, parties, school events and smart-casual occasions.
A boys suit jacket is normally designed as part of a matching suit, with trousers made from the same fabric and colour. If you need a fully coordinated jacket-and-trouser outfit, browse our Boys Suits.
How to Wear a Boys Blazer Casually
A blazer does not have to be reserved for formal occasions. For a smart-casual outfit, pair a boys blazer with chinos, a simple shirt or polo, and loafers or other smart shoes.
Plain navy, blue, beige and grey blazers are particularly easy to dress up or down, while patterned and textured jackets can add more personality to a simple outfit.
