The Shoulder of a Jacket: Natural, Roped and Structured

Ask a tailor which part of a jacket he worries about and he will not say the waist or the length. He will say the shoulder. Everything else can be opened, moved and closed again. The shoulder is built once, from several layers shaped against one another, and it holds the garment on the body. Get it right and the jacket looks alive. Get it wrong and nothing done further down will rescue it.

It is also the part almost nobody looks at. Here is what we are examining when we stand behind you at a fitting and say nothing for a moment.

Why the shoulder decides everything

A jacket hangs from two points, and they are not the buttons. The cloth is suspended from the shoulder seams and falls from there over the chest and the blades, which means the shoulder sets the direction of every fold below it. A shoulder a quarter of an inch too wide sends a wave of cloth down the top of the sleeve. One set too square against a sloping body lifts the collar off the neck. One cut too narrow pulls a crease from the armhole toward the chest the moment you reach for a door.

This is why we take three photographs along with about thirty measurements at the consultation. A tape tells us how wide you are across the back. Only a photograph from behind tells us that one of your shoulders sits lower than the other, which it almost certainly does. Posture is a measurement, and the shoulder is where it shows.

What is inside a shoulder

Lift the lining of a well made jacket at the shoulder and four things are working together. The canvas, the inner layer of horsehair and wool that shapes the chest and is stitched, not glued, in every garment we make. The shoulder pad, which may be a quarter of an inch of wadding or almost nothing. The sleeve head, a narrow roll of wadding or felt set into the top of the armhole to stop the sleeve collapsing. And the way the sleeve is set in, which is hand work, and where a maker either earns the money or does not.

Those four decisions together are what people mean by shoulder construction, and they rest on the layer beneath, which we cover in full canvas, half canvas and fused construction. Every garment this house makes is full canvas, the only sensible foundation for a shoulder meant to hold its shape for twenty years.

The natural shoulder, and spalla camicia

A natural shoulder follows the line of your own with little or no padding. It is Neapolitan in origin and the softest of the three. The wadding in the sleeve head is reduced to a whisper or left out entirely, so the jacket reads more like a cardigan than armour. On a man with square shoulders and some width to begin with, it is the most flattering thing we can cut.

Spalla camicia, which means shirt shoulder, is the Neapolitan extreme of this. The sleeve is set into the armhole the way a shirt sleeve is, from the inside, with a little extra cloth gathered along the top. That gathering shows as fine puckers along the seam. It is deliberate hand work, it gives the arm enormous freedom, and it makes a jacket unmistakably Italian, so we would not put it on one you intend to wear in a courtroom.

The roped shoulder

A roped shoulder, the Milanese and English answer, builds the sleeve head up so that the top of the sleeve stands slightly above the shoulder seam in a small ridge, like a rope laid along the join. It lifts the line, squares the silhouette and lengthens the look of the chest.

Roping is a matter of degree rather than a switch. A light rope on an otherwise soft jacket gives a clean, definite line without any theatre. A heavy rope with a firm pad is the full English city silhouette, marvellous on a man with the height to carry it. Our piece on British, Italian and American suit styles sets out how the rest of a jacket follows the shoulder you choose.

The structured shoulder

Structured simply means more padding and a firmer canvas, with or without roping. Its honest purpose is correction. A man with a pronounced slope, or a narrow frame he would like to read wider, is served by structure in a way no amount of softness will manage. The mistake is to use it as a style rather than as a remedy, since a heavy pad on a man who is already square gives him the outline of a doorway. We build the least structure that solves the problem, and we build each side separately, because the two sides of a body are not the same.

How to judge a shoulder that fits

Stand square in front of a mirror with your arms down and look for four things. The shoulder seam should end where your own shoulder ends, where the flat top turns down into the arm. The top of the sleeve should run smooth, with no dent where the pad stops and no wave along the outer third. The collar should lie flat against your shirt collar all the way round. And the upper back should be quiet, with no diagonal lines running toward the neck or the armhole.

Then move. Reach forward, cross your arms, put a hand in a hip pocket. A shoulder and armhole cut properly will let you do all three without the jacket lifting off your neck. There are more checks of this kind in our guide to how a suit should fit.

Why a shoulder cannot be fixed afterwards

This is the part worth remembering if you ever buy a jacket off the peg. Sleeves can be shortened, a waist taken in, a seat let out. The shoulder is a different matter, because to narrow it a maker must detach the sleeve, reshape the canvas, recut the armhole, rebuild the sleeve head and set the sleeve again in balance, on both sides. That is most of the labour of making a jacket, done on a garment never drafted for you.

So the shoulder is the one measurement to buy correctly, and it is the single strongest argument for a pattern drafted to your own frame. We no longer take alterations in as a separate job, and we do not work on garments made elsewhere, which means our honest answer to a jacket with a bad shoulder is that it cannot be put right. On the garments we make, a year of complimentary alterations is included, and we keep looking after them long after that.

What we usually suggest

For a first navy or charcoal suit meant to work everywhere, a soft shoulder with a very light rope. It reads as tailoring rather than as a style statement and suits almost every frame. For a city wardrobe with a boardroom in it, more structure and a definite rope. For custom blazers and sport coats, the softest shoulder you are comfortable with, since a jacket worn without a tie wants to look easy.

None of this is decided on paper. We drape the cloth over your shoulder, pin it, and you look in the mirror, which settles the argument in a minute. Our account of what happens at a suit fitting explains the stages, and making runs four to twelve weeks.

Questions we are often asked

What is a natural shoulder on a suit?

A shoulder cut to follow your own shoulder line with little or no padding, Neapolitan in origin and the softest of the three usual choices. The sleeve head is reduced or left out, so the top of the sleeve falls rather than stands. It flatters a man who already has square shoulders and some width, and it reads as relaxed, which is why it belongs on a jacket worn without a tie more readily than on a formal city suit.

What does spalla camicia mean?

Shirt shoulder, in Italian. The sleeve is set into the armhole the way a shirt sleeve is, from the inside, with a little extra cloth gathered along the top seam so that fine puckers show along the join. It is hand work and it is intentional, not a fault. It gives the arm a great deal of freedom and marks a jacket out as Italian, so we use it where a soft, informal jacket is wanted.

What is a roped shoulder?

A shoulder where the sleeve head is built up so the top of the sleeve stands slightly proud of the shoulder seam in a small ridge, like a rope laid along the join. It is English and Milanese in character. It squares the silhouette and lengthens the chest. Roping is a matter of degree, from a whisper on an otherwise soft jacket to the full city line on a firmly padded one.

How do I know if a jacket shoulder fits?

Four checks in a mirror, arms down. The seam ends where your shoulder ends, at the point the flat top turns into the arm. The top of the sleeve is smooth, with no dent where a pad stops and no wave along the outer third. The collar lies flat against your shirt collar all the way round. The upper back is quiet, with no diagonal creases toward the neck or the armhole. Then reach forward and cross your arms, and see whether the collar stays put.

Can a tailor fix a shoulder that is too wide?

Not sensibly. Narrowing a shoulder means detaching the sleeve, reshaping the canvas, recutting the armhole, rebuilding the sleeve head and setting the sleeve again in balance on both sides, which is most of the labour of making a jacket. We no longer take alterations in as a separate job, and we do not work on garments made elsewhere, so our answer on a bought jacket is that the shoulder is the one thing to get right at the point of purchase.

Which shoulder suits narrow shoulders?

A little structure and a light rope. Both lift and square the line, which reads as width without adding bulk anywhere else. We would keep the pad modest, because a heavy pad on a narrow frame looks like a borrowed coat, and we would balance the two sides separately, since one shoulder is nearly always lower than the other.

Does a softer shoulder make a jacket less formal?

Slightly, yes. The firmer and squarer the shoulder, the more formal the jacket reads, which is why evening and city tailoring tends to be built up and a linen jacket tends not to be. The effect is small compared with cloth and colour, so a soft shoulder in a dark worsted is perfectly correct in any office. We would not put a shirt shoulder on a dinner jacket.
