Suits Built for Teens, Not Boys

There's a moment when a "boys suit" stops fitting — not just in the shoulders, but in the style. Teenagers want a suit that looks like something they'd actually choose: slim through the body, modern in the lapel, cut like the suits they see, not a scaled-up kids' costume. That's exactly what our teen suits collection delivers, in youth sizes 14 through 20, with slim and husky fits for every build.

NorthBoys is Canada's only dedicated boys' and teens' clothing store, and teen formalwear is our specialty. We fit thousands of teens each year for graduations, proms, bar mitzvahs, and weddings from our three Toronto-area locations — and ship across Canada with free shipping available.

The Right Suit for Grad, Prom, and Every Big Moment

Grade 8 and high school graduation. A slim-fit suit in navy, grey, or black delivers a sharp, grown-up look for the ceremony and photos — and re-wears for every formal event that follows.

Prom and semi-formal. Stand-out colours, modern stretch fabrics, and tailored silhouettes. Pair with a skinny tie or go open-collar — our team can style the full look.

Bar mitzvahs. Whether he's the bar mitzvah boy or a guest, we fit teens for these celebrations every week. Stretch-fabric suits move with him from the service to the party, and our Lawrence Plaza and Hillcrest Mall teams know exactly what the occasion calls for.

Weddings and family events. Junior groomsman, cousin's wedding, holiday dinner — a properly fitted teen suit handles them all.

Sized for the In-Between Years

Teen bodies change fast, and standard sizing rarely keeps up. That's why we carry sizes 14, 16, 18, and 20 in slim and husky fits, and why many of our suits are sold as separates — so a teen with a size 18 chest and a size 16 waist gets a real fit in both pieces. If he's outgrowing youth sizing altogether, our largest sizes bridge the gap to men's suiting without the men's price tag, and our in-store fitters can tell you in five minutes exactly where he lands.

Designer Labels and Modern Stretch Fabrics

Our teen collection features Hugo Boss, Tallia, Michael Kors, and Marc New York, alongside Nice Threads — our exclusive in-house label of slim-fit stretch suits, available only at NorthBoys. Nice Threads suits are built with four-way stretch fabric that keeps a tailored shape while letting him move, dance, and sit through a three-hour event without complaint. They've become our best-selling teen suits for good reason.

Everything to Complete the Look

Dress shirts, skinny and classic ties, bow ties, belts, dress shoes, and socks — all coordinated to our suit colours. Walk out (or check out) with the complete outfit in one stop.

Teen Suits FAQ

What size suit does a teenager wear?
Most 13–14 year-olds wear a youth size 14–16, and most 15–17 year-olds wear a youth 18–20 — but height and build matter far more than age. Measure his chest and waist against our size guide, and if he's between sizes, size up. Suits sold as separates let you match jacket and pant sizes independently.

When should a teen move from youth sizes to men's suits?
When his chest measurement exceeds a youth size 20 (roughly a 36–37" chest), it's time for men's sizing. Our fitters can measure him in minutes and tell you exactly where he lands — many teens fit our size 18–20 suits far longer (and at a lower price) than parents expect.

What suit should a teen wear to prom or grad?
A slim-fit suit in navy or charcoal is the safest sharp choice, and stretch fabrics are worth prioritizing — he'll be sitting, dancing, and posing for photos for hours. For prom, bolder colours and textured fabrics are on-trend; for graduation, classic shades photograph best and re-wear the longest.

Do you carry husky fit suits for teens?
Yes. Our husky fits add room through the chest, waist, and seat without extra length, in sizes up to 20 — one of the widest teen husky selections in Canada.

Can I get a teen suit shipped anywhere in Canada?
Yes — we ship across Canada with free shipping available, and to the United States. If you're working against an event date, contact us and we'll confirm timing before you order.

Do teen suits need tailoring?
Often just a pant hem, which any local tailor handles in a day or two. Because we carry three fits and sell many suits as separates, most teens leave with a near-perfect fit off the rack — that's the advantage of a store built specifically for boys and teens.
