Boys' clothing
Boys' clothing at Hackett London earns its place in a wardrobe that has to survive school, Saturday football and everything in between.
Getting the size right first
Hackett London offers two size references for boys' clothing — by age and by height. For boys slimmer or sturdier than average, height sizing usually gives the more reliable result, an approach the brand has stuck to since its first boutique opened on Savile Row's doorstep in King's Road in 1983. Leaving room to grow at the waist and sleeve length means a piece earns more than one season's wear.
Fabrics built for skin and movement
Combed cotton runs through t-shirts and shirts, with a soft surface that doesn't scratch or irritate after hours of wear. Knitwear and trousers carry a small percentage of elastane — rarely more than 3-5% — giving the ease needed to run or crouch without losing shape, the same material discipline the brand applies on Jermyn Street's dress shirts.
How to combine boys' clothing from Hackett
Two ways to work the same base pieces:
Grey knit jumper over a white shirt and chino trousers: the tidy option for a school day.
The same jumper over jeans and trainers: the register drops for a Saturday out without losing the brand's look.
What's the difference between age and height sizing in boys' clothing?
Age sizing is a rough guide that doesn't account for build, while height sizing follows actual stature and usually fits better between two sizes. If a boy falls between two ages, height sizing is the safer choice.
Is Hackett boys' clothing sturdy enough for daily school wear?
Yes, pieces include reinforced seams and heavier fabric at high-wear points like knees and elbows. This lets them withstand playground wear and several weekly washes without losing shape.
What age range does the Hackett boys' collection cover?
The collection generally runs from around age 4 to 16, with different cutting logic for younger and older boys. From about 4-5, blazers and shirts start to pick up the proportions of the adult line.
