How a suit should actually fit

Most advice about suit fit is written backwards. It starts with the things that are easy to photograph — sleeve length, trouser break, how much shirt cuff shows — and never mentions the things that decide whether a suit is right or wrong. So here is the order a cutter actually checks, from the fitting-room floor.

Shoulders first, always

The shoulder seam should end where your shoulder ends — not a centimetre past it, not digging inboard of the bone. Cloth across the back should lie flat when your arms hang naturally. If the shoulders are wrong, stop looking. Nothing else can be fixed around them, and any tailor who says otherwise is selling you an expensive compromise.

Why so absolute? Because the shoulder is the suit’s foundation: the entire weight of the garment hangs from it, and every wrinkle below is usually a symptom of a problem up top.

Balance second

Balance is the trade’s word for whether the jacket hangs level on your particular posture. Stand side-on to a mirror: the front and back hems should sit level, the collar should hug your shirt without a gap, and the lapels should lie against the chest without springing open.

A person who stands very upright tips a standard jacket backwards; a desk-rounded back tips it forward and throws a collar gap. Ready-to-wear cannot see your posture. This single point is most of the argument for bespoke.

Then, and only then, the details

• Chest: your flat hand slides in under the lapel; a fist strains the button.
• Waist: shaped, not strangled. The button closes without an X of tension lines.
• Length: the jacket covers the seat; your knuckles roughly meet the hem.
• Sleeve: ends at the wrist bone, showing about a centimetre of shirt cuff.
• Trouser: one soft break, or none if the leg is trim. Puddles are not a style.

The test nobody runs

Sit down. Drive an imaginary car. Reach across a table to shake a hand. A suit judged only standing still is a suit judged for photographs, and you do not live in photographs. At our fittings you will be asked to sit, cross your legs and fold your arms while we watch what the cloth does — that is the fit inspection that matters.

And if a jacket you already own passes the shoulders-and-balance test but fails the details, take it to a good alteration bench before replacing it. That is honest arithmetic — and if you need a bench, ours is here.
