How a suit should fit: the tailor's checklist
Updated July 2026 · Sam’s Menswear editorial team
A suit fits when the shoulder sits clean on your shoulder, the chest closes without pulling, and a little shirt cuff shows past the jacket. Everything else is refinement. Here’s the checklist I run at every fitting, in the order that matters.
1. Shoulders: the one that matters most
The shoulder seam should end right at the edge of your shoulder: no dent pressing in, no overhang flopping off. This is the hardest thing to alter after the fact, which is why an off-the-rack suit with wrong shoulders is a lost cause. Get this right and the rest is easy.
2. The chest & button
Button the jacket. It should close cleanly with no X-shaped pull across the button, and you should be able to slip a flat hand inside the lapel, snug but not straining. A gaping collar or a pulling button means the balance is off.
3. The sleeve & cuff
The jacket sleeve should stop at the wrist bone and let about a quarter- to half-inch of shirt cuff show. No cuff means the sleeve is long; too much means it’s short. Sleeve length is a quick fix. Sleeve pitch (the forward hang of your arm) is a tailor’s job.
4. Jacket length
The hem should cover your seat and roughly split the distance from collar to floor. Too short reads trendy-then-dated; too long shortens your legs. On a bespoke jacket I cut this to your actual proportions, not a size chart.
5. Waist & trousers
The jacket should trace a gentle taper at the waist: shape, not a corset. Trousers sit at the waist without a belt cinching them shut.
6. The break
The break is where the trouser meets the shoe: full, half, or none. It’s a matter of taste, so I show you each on you before we finish the hem, rather than deciding for you.
