Boys Blazers by Colour

Navy & Blue Boys Blazers

A boys navy blazer is one of the most versatile choices for weddings, school events, parties and family occasions. Navy and blue blazer jackets pair easily with grey, beige or navy trousers and a white or pale-blue shirt.

Black Boys Blazers

A boys black blazer creates a clean, formal look for evening events, ceremonies, parties and special occasions. Pair it with black or grey trousers for a traditional outfit, or contrast it with lighter trousers for a more modern finish.

Grey & Beige Boys Blazers

Boys grey blazers work well throughout the year and can be dressed up or down depending on the occasion. Beige and stone blazer jackets are particularly suitable for spring, summer and destination weddings.

Green, Burgundy & Statement Colours

Green, burgundy and richer seasonal colours offer an alternative to traditional navy, black and grey. These shades work especially well when the blazer is intended to be the main feature of the outfit.

Boys Blazers for Weddings & Formal Occasions

A boys blazer is an easy way to create a smart wedding or occasion outfit without choosing a full matching suit. Pair a blazer with a crisp formal shirt, tailored trousers and smart shoes for weddings, parties, ceremonies and family celebrations.

Velvet and darker jackets create a more formal evening look, while linen, lighter colours and softer tailoring are ideal for spring and summer weddings.

Toddler Boys Blazers & Kids Blazers

Our collection includes toddler boys blazers, kids blazers and teenage styles, making it easy to find smart jackets for younger children through to boys aged 16.

For toddlers and younger boys, look for a comfortable fit that allows easy movement through the shoulders and arms. Older boys and teenagers may prefer slimmer or more structured blazer jackets for a sharper, more grown-up look.

For younger baby-specific sizes and styles, browse Baby Boys Blazers.

Boys Blazer vs Suit Jacket: What’s the Difference?

A boys blazer is normally designed to be worn as a separate jacket, so it can be paired with different trousers, shirts and shoes. This makes it a flexible choice for weddings, parties, school events and smart-casual outfits.

A boys suit jacket is usually 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 boys blazer jacket does not have to be reserved for formal occasions. For a smart-casual outfit, pair it with chinos, a simple shirt or polo and loafers or other smart shoes.

Plain navy, blue, beige and grey kids blazers are particularly easy to dress up or down, while patterned, tweed and textured jackets add more character to a simple outfit.

Complete the Look

Pair his blazer with a crisp Boys Formal Shirt and Boys Formal Trousers or chinos.

Complete a formal outfit with Boys Brogues & Oxford Shoes, then add a tie, bow tie or pocket square from our boys accessories range.

If you prefer a fully coordinated outfit rather than separates, browse our complete Boys Suits collection.

For coordinated family styling, explore Father & Son Blazers.

How should a boys blazer fit?

The shoulders should sit neatly without extending beyond the natural shoulder line. The jacket should button comfortably and leave enough room for a shirt underneath without pulling across the chest.

How do I choose the right boys blazer size?

Measure his height, chest and sleeve length and compare the measurements with the individual product size guide. Measurements are generally more reliable than choosing a blazer based only on age.
