The short answer
At a fitting, describe what you feel and see rather than the fix you think is needed: "it pulls across my back when I reach forward" beats "let the back out". Check from the top down: collar, shoulders, chest and button, back, length, sleeves, then trousers. Move, sit and reach, use a three-way mirror, then repeat each agreed change back to the tailor before you leave.
- Describe the feeling, the place and the movement; leave the fix to the tailor.
- Check from the top down, because the collar and shoulders affect everything below them.
- Stand naturally, then reach, raise your arms, sit and walk.
- Raise big changes at the first fitting, when they are cheapest to make.
- Before you leave, repeat each change back and agree what will look different next time.

Many people stand silently at a fitting, nod at everything and only realize what bothered them once they get home. The tailor sees how the suit looks from the outside; only you know how it feels from the inside. Good feedback joins those two views. It takes no technical vocabulary, just a few habits: describe instead of diagnosing, check in a set order, test the suit by moving, and confirm every change before you go.

How do you describe fit problems to a tailor?
Say what you feel, where you feel it and when. "It's tight across my shoulder blades when I reach for the steering wheel" tells the tailor the problem, its location and the movement that causes it. "Let the back out" tells them your guess at a cure, which may be wrong: the same tightness can come from the back width, the armholes or the angle of the sleeves.
Preferences are different from problems, and they are worth saying just as plainly. "I'd like the jacket a little shorter", "I prefer a bit more room in the thigh" and "I'd like less break on the shoe" are clear instructions about taste. A good tailor will tell you if a preference works against your build or the house style, and why.
Which words describe common fit problems?
You do not need the tailor's vocabulary, but it helps to know what you are looking at. The table pairs what you might notice with a plain way to say it and the areas a tailor will usually check. The tailor decides the cure.
| You notice | Say | The tailor will look at |
|---|---|---|
| A gap between the jacket collar and your shirt collar at the back | "The collar stands away from my neck." | Collar fit, shoulder slope and how you stand |
| A horizontal ridge of fabric just below the collar at the back | "There's a fold below the collar." | Collar length, back balance and upper-back width |
| A dent or ripple at the top of the sleeve, below the shoulder | "There's a dent below my shoulder." | Shoulder width, padding and the sleeve head |
| Diagonal folds running from the collar toward the armpits | "There are lines from my neck to my armpits." | Shoulder slope |
| An X of pull lines around the fastened button | "It pulls at the button." | Waist and chest width, button position |
| The fronts swing apart or cross over below the button | "The fronts open (or overlap) below the button." | Balance: the front and back lengths |
| The sleeve twists, with folds at the back or front of the upper arm | "The sleeve twists on my arm." | Sleeve pitch, the angle the sleeve is set at |
| Tightness across the shoulder blades when you reach | "It's tight across my back when I reach forward." | Back width, armholes and sleeve pitch |
| The whole jacket rises when you lift your arms | "The jacket lifts when I raise my arms." | Armhole height and sleeve shape |
| The vent pulls open while you stand still | "The vent opens when I'm standing." | Seat and hip width |
| Creases fanning out from the crotch at the front of the trousers | "There are creases fanning from the crotch." | Front rise and thigh width |
| Loose folds of fabric under the seat | "There's spare fabric below my seat." | Seat shape and back rise |
| Front trouser pockets that pull open | "The pockets gape." | Hip width |
| A waistband that digs in or drops when you sit | "The waist digs in when I sit." | Waist size and rise |
These are the usual first suspects, not diagnoses. Several problems share causes, which is why describing beats prescribing.

What should you check at a fitting, and in what order?
Check from the top down. The collar and shoulders carry the jacket, so a problem there causes folds and pulls further down. If you start with the sleeve length, you may chase a symptom of a shoulder problem. Leave lengths until last, because they are the easiest to change.
Stage 1: Collar
Rests on your shirt collar all the way round, with no gap at the back
Stage 2: Shoulders
End where your shoulders end, with no dents or overhang
Stage 3: Chest and button
Lapels lie flat; no X of pull lines at the button
Stage 4: Back
Clean, with no ridge below the collar and no diagonal drag
Stage 5: Balance and length
Hem level all round; jacket length as you want it
Stage 6: Sleeves
Hang straight without twisting, then length
Stage 7: Trousers
Waist, seat, rise and leg, then length against your shoes
At a basted first fitting, ignore the finish completely. Loose threads, raw edges and chalked pocket positions are the point of a baste. Our guide to bespoke fittings explains what the cutter is checking at each stage, and your first fitting covers what to wear and bring.
How should you use the mirror at a fitting?
The mirror is for checking, not posing. These habits give you an accurate view.
- Let the tailor look first. Stand still facing forward while the tailor works round you. Turning to the mirror changes how the suit hangs.
- Stand as you normally do. Weight on both feet, arms by your sides, breathing normally. Do not pull in your stomach or straighten up for the mirror.
- Use a three-way mirror to see the side and back, which you never see at home. If there is none, ask the tailor or a friend to take photos of your back and side.
- Compare both sides. Most people have one shoulder lower than the other; check that the collar, shoulders and sleeves look even.
- Look from a distance. Step back so you see the whole suit at once. Proportions such as jacket length and lapel width read better from 6 feet (about 2 m) away.
- Look at the suit, not your face. Follow the edges: the collar, the lapel line, the hem and the trouser crease.
Which movements should you test at a fitting?
A suit that looks perfect while you stand still may pull, rise or dig in as soon as you move. Run through these tests at every fitting, and say what you feel during each one.
Movement tests, in order
- 1
Stand still for a minute
Let the suit settle on your body before anyone judges it. Breathe normally and keep your arms relaxed by your sides.
- 2
Reach forward
Hold your arms out as if gripping a steering wheel or hugging someone. Notice any tightness across the back or under the arms, and how far the sleeves ride up.
Tip: Some tightness when reaching is normal in a fitted jacket. Pain or a seam that strains is not.
- 3
Raise your arms
Lift your arms to shoulder height, then overhead. Watch how far the whole jacket rises and whether the collar lifts away from your neck.
- 4
Fold your arms and check a watch
This shows elbow room and whether the sleeves are long enough when your arms bend.
- 5
Sit down, lean back and cross your legs
Unbutton the jacket first. Check whether the waistband digs in, the seat pulls, the thighs feel tight and the trousers ride too high up your shins.
- 6
Walk and take a high step
Walk across the room and lift one knee as if climbing a stair. Notice any pull at the crotch or thighs and whether the trouser leg falls back cleanly.
- 7
Fill your pockets
Put your phone, wallet and keys where you will really carry them. A phone in the inside breast pocket changes how the front hangs, and the tailor can allow for it.
- 8
Turn your head
Look over each shoulder. The collar should stay close to your neck rather than standing away.
What can be changed at each fitting?
The earlier the fitting, the more can change. At a bespoke baste, almost everything is still open; by the finish fitting, mostly lengths and small adjustments remain. Altering a finished ready-made or made-to-measure suit is limited by the fabric left in its seams. Time your feedback to match.
| Baste | Forward | Finish | Altering a finished suit | |
|---|---|---|---|---|
| Jacket length | ||||
| Shoulder width or slope | ||||
| Collar gap | ||||
| Jacket waist | ||||
| Sleeve twist (pitch) | ||||
| Sleeve length | ||||
| Button position | ||||
| Lapel width or shape | ||||
| Pocket position | ||||
| Trouser waist and seat | ||||
| Trouser length |
On a ready-made suit, the limits are set by the seam allowances. Our guide to what a tailor can alter explains what can be done, and suit sleeve length and trouser break cover the two lengths you will discuss most.
How do you agree changes with your tailor?
Most fitting disappointments come from changes that were discussed but never clearly agreed. Close every fitting the same way.
- 1.Ask the tailor to explain each pin and chalk mark. "What will this change?" is a perfectly normal question.
- 2.Repeat the changes back in your own words: "So the jacket comes in at the waist, the left shoulder drops slightly and the trousers lose half an inch."
- 3.Say what matters most. If one thing bothers you more than the rest, say so, so it gets the most attention.
- 4.Ask what will look different next time, so you know what to check.
- 5.Take photos of the pins with the tailor's agreement, and write a short note of the changes. A brief email after the fitting gives you both a record.
- 6.Ask about cost if you have asked for a change of design rather than fit, and confirm whether it is included.
- 7.Book the next fitting before you leave, and check each agreed change when you return.
What if you and the tailor disagree?
Ask why. The tailor may know something the mirror does not show: a basted sleeve is often left long on purpose, a fabric may relax after pressing, and a house style has reasons behind it. But it is your suit. Explain how you will wear it, at a desk, on a bicycle, in heat, and what you dislike about suits you already own. If you still differ, agree to look again at the next fitting rather than forcing a decision.
What are the most common feedback mistakes?
- Diagnosing instead of describing. Naming a fix can send the tailor after the wrong problem.
- Standing to attention. Holding your breath or pulling your shoulders back gets you a suit cut for a posture you never use.
- Judging the baste on its finish. Raw edges and loose threads are meant to be there.
- Wearing different shoes or shirts each time. Heel height sets the trouser length and the shirt cuff sets the sleeve.
- Bringing a crowd. One trusted opinion helps; three opinions confuse the fitting.
- Saving complaints for the end. The finish fitting is the most expensive time to raise a big change.
- Agreeing to be polite. A tailor would rather hear a doubt now than see you unhappy later.
- Changing weight between fittings. Tell the tailor if your weight has moved, so they can judge what is the suit and what is you.
The tailor's view
The most useful customer at a fitting is not the one who knows the vocabulary but the one who notices how a garment feels and says so honestly. A tailor can see a collar gap; they cannot feel the tightness when you reach for a bag on a train. Give them that information, in plain words, at every fitting, and let them translate it into chalk.
If you are still choosing a tailor, our list of questions to ask a tailor helps you find one who listens, and how a suit should fit sets out the standard to aim for.
Questions people ask
How do I tell my tailor what I want?
Tell your tailor what you feel, where and when, such as "it's tight across my back when I reach forward", rather than naming a fix. For style preferences, say them plainly and bring two or three photos of suits you like. The tailor can then translate both into changes to the pattern.
Is it rude to ask a tailor for changes at a fitting?
No. Asking for changes is the purpose of a fitting, and good tailors expect and welcome it. They would much rather hear a concern at the first fitting, when it is easy to fix, than find out you are unhappy after the suit is finished.
How tight should a suit feel at a fitting?
A suit should feel close but comfortable at a fitting: you should be able to reach forward, raise your arms and sit without seams straining or the waistband digging in. Some tightness across the back when you reach is normal in a fitted jacket. If anything pinches, restricts movement or makes you hold your breath, say so.
Should I bring someone to a suit fitting?
Bringing one person whose judgment you trust can help, especially to take photos of your back and give a second view. Bringing several people usually confuses the fitting, because opinions conflict and the tailor cannot tell whose wishes to follow. The final say should always be yours.
What if I'm not happy after the final fitting?
If you are not happy after the final fitting, say so to the tailor before you collect the suit, and describe exactly what bothers you and when you notice it. Most tailors will make further adjustments to their own work. Check the written terms for any time limit on reporting problems after collection.
Can I take photos at a suit fitting?
Most tailors are happy for you to take photos at a fitting, but ask first. Photos of the back and side help you see what the mirror hides, and photos of the pins and chalk marks give you a record of what was agreed to check at the next fitting.
