The Anatomy of a Perfect Fit

Collar gaps, restricted armholes, and trouser break — fit is a technical language. Understanding the anatomy of how a suit should sit on your body is the first step toward demanding perfection.

A bespoke suit is an engineering marvel — hundreds of pattern pieces, thousands of stitches, and dozens of construction decisions converging into a single garment that moves with you. But no amount of craftsmanship can compensate for a poor fit. When we speak of fit at Regal Stitch, we are speaking of precision measured in millimetres: the fraction of an inch that separates acceptable from extraordinary. This guide will teach you to see what our tailors see, so you can understand — and demand — true perfection.

The Collar: The Most Critical Junction

The collar is where the jacket meets the shirt, and it is the single most visible indicator of proper fit. A well-fitted collar should lie flat against the shirt collar without any gap — that tell-tale space between jacket and shirt that signals a ready-to-wear compromise. The jacket collar should rest lightly on the shirt collar, following the natural curve of the neck without pressing or bunching. Collar gaps typically indicate that the jacket's chest is too wide, the back is too long, or the shoulder angle does not match the wearer's frame. In bespoke tailoring, the collar is reshaped at every fitting until it sits with surgical precision.

Shoulders: The Foundation of Silhouette

The shoulder seam should terminate exactly where your natural shoulder ends — not a centimetre before or beyond. When the shoulder extends too far, the jacket creates a shelf effect that ages poorly and distorts the silhouette. When it falls short, it creates unsightly bunching and restricts arm movement. The shoulder itself should follow the natural slope of your body, neither padding beyond your frame nor collapsing inward. At Regal Stitch, we sculpt the shoulder head by hand, building a clean, natural line that appears effortless but requires extraordinary skill to achieve.

The Chest and Button Stance

The chest of the jacket should conform to your torso without pulling, bunching, or creating horizontal stress lines across the buttoning point. When you button your jacket, you should be able to slip a flat hand between the jacket and your shirt — no more, no less. The button stance — the vertical position of the top button — determines the visual proportion of the jacket. A higher stance elongates the torso and suits leaner builds; a lower stance broadens the chest and complements stockier frames. This is one of the most powerful tools in a bespoke tailor's arsenal, and it should never be left to chance.

Armholes: The Mark of Quality

The armhole is perhaps the most technical element of jacket construction and the clearest dividing line between bespoke and off-the-rack. A properly cut armhole sits high and close to the body, following the natural joint where arm meets torso. This positioning allows the jacket to move independently of the shirt beneath — you can raise your arms without pulling the entire jacket upward. Low, wide armholes — common in ready-to-wear — restrict movement and create unsightly fabric pull. When you try on a bespoke jacket for the first time, raise your arms. If the jacket stays put while your arms move freely, the armholes are correct.

Jacket Length and Vent Placement

The ideal jacket length should cover your seat entirely, with the hem falling at the base of your thumb when your arms hang naturally at your sides. Too short, and the jacket appears cropped and modern in a way that sacrifices elegance. Too long, and it overwhelms your proportions. The vents — whether single or double — should lie flat against the body when standing and open gracefully when walking. Double vents are the hallmark of British tailoring and offer superior ease of movement; single vents suit a leaner, more contemporary silhouette. Each option has its merits, and the choice should be made in consultation with your tailor based on your build and wardrobe.

Trouser Fit: From Waist to Hem

Trousers are the unsung heroes of a well-fitted suit. The waistband should sit at your natural waist — typically just below the navel — and remain comfortable without a belt. Suspenders, or braces, are the traditional choice for bespoke trousers because they allow the fabric to drape cleanly without the bunching that belts introduce at the waist. Through the hip and thigh, the trouser should follow the body's contour without clinging. The knee should articulate freely, and the hem should break once — a gentle fold where the trouser meets the shoe — before falling straight. This single break creates a clean, timeless line that flatters virtually every build.

Fit is not subjective — it is technical, measurable, and absolute. When every element of your suit is calibrated to your body, the result is not merely clothing but an extension of yourself. At Regal Stitch, we have spent years refining the art of fit so that every client experiences the quiet confidence that comes from wearing something made exclusively, precisely, and unapologetically for them.
