Your suit pulls when you raise your arms because the armhole is cut too low and too wide — almost never because the jacket is "too small". A low armhole joins the sleeve to the body far down your ribcage, so your arm drags the whole jacket up with it. A high, close-cut armhole lets the body sit still while only the sleeve moves. That one dimension explains most of what people blame on price, fabric, canvas or "cheap tailoring".
I am Jay. I spent about ten years in the US — Pennsylvania, New York, Houston — buying suits that looked fine standing still and fought me the moment I moved. A year ago I came to Hoi An as a customer of Nathan Tailors and liked it enough to become a partner. Linda, born and raised here, twenty-five years at the cutting table, leads the craft. This is her answer to my most annoying question, plus the receipts.
Why does a suit pull when you raise your arms?
Picture the jacket as two pieces joined in a ring under your arm. That ring is the armhole — cutters call it the armscye — and where its bottom sits on your ribcage decides everything.
Sitting low — two or three fingers below the armpit — it attaches a large area of the jacket body to the sleeve. Lift your arm and the sleeve pulls all of it: the front rides up, the collar leaves your neck, the lapels bow. Sitting high, tucked under the armpit, the sleeve is attached to a much smaller patch, and the jacket stays where it was while you lift, reach and drive.
The counter-intuitive part — and the part almost every shopper gets backwards — is that a high, tight-looking armhole gives you more movement, not less. It looks restrictive on a hanger. It is the opposite in wear. One commenter under the Gentleman's Gazette video summed up the hierarchy in a line: "cheap suit = fused, machine made, low armholes. bespoke = fully canvassed, handmade, high armholes."1
Why cut a low armhole at all? It is cheaper and safer: it fits more bodies without complaint in the fitting-room mirror, needs less precision, and sews faster. It only fails when the customer moves — which happens after the sale.
Why does a $5,000 suit not pull when you raise your arms?
That is a real search phrase, taken almost verbatim from a comment under Gentleman's Gazette's $500-vs-$5,000 suit video: "how does the 5k suit not tighten up when raising up your arms? Does $5,000 fabric magically increase in length from under your armpits?"1 No, the fabric does not stretch. Three things differ, and none is the price tag:
- The armhole is higher and smaller, so less of the jacket is attached to the moving sleeve.
- The sleeve is set at the right pitch for that person's arm hang, so it does not fight the shoulder at rest or at the top of the reach.
- The shoulder slope matches the wearer. As the video's presenter puts it, a good cutter "could see right away that you have a sloping shoulder" — and watches how you move before cutting.1
Now the honest part, because here the comment section beats the video. Viewers caught the demo being unfair: "you didn't make the same movements in the expensive jacket that you did with the inexpensive jacket" — and, at 67 likes, "I would have liked to see you sir stretch out both your arms while wearing the expensive suit, buttoned up."1 They are right. It was staged toward its conclusion — and the conclusion is still true. The mechanism does not need the demo; you can test it in ten seconds, as below.
The armhole is the only part of a jacket where "tighter" and "more freedom" are the same instruction.
One comment cuts against the $5,000 number hard: "I got two suits from a local tailor that cost me 189.00... When I raise my arm straight up, the suit moves with me."1 A high armhole is a cutting decision, not a budget — available at almost any price, just not the default at most of them.
Suit arm holes too big and the jacket lifts when raising arms — isn't bigger roomier?
No — and this is the most useful thing in the post. A two-star review of a budget three-piece names it perfectly: "Material is nice, sizing is pretty accurate. Major con: the arm holes are way too wide so when you raise your arms, the whole jacket lifts."2
Sizing accurate. Material nice. Jacket unwearable when he moves. No size change fixes that, because armhole depth scales with the size — going up gives you a bigger armhole and a worse lift. It runs the other way too: "I purchased a size 52 tall and it was still so tight in the shoulders I couldn't fold my arms."5 Four sizes up did not fix a shoulder problem, because shoulder width and shoulder slope are separate variables and only one moves with the size label.
What is sleeve pitch, and is that why my sleeve twists?
Sleeve pitch is the rotation of the sleeve inside the armhole — a clock face set a few minutes forward or back before it is stitched in. Everyone's arms hang slightly forward, by different amounts. Set the sleeve straight down on a forward-hanging arm and it fights you: a diagonal wrinkle from the back of the shoulder toward the elbow at rest, and a twist along the arm when you reach. It is not a tightness problem — the sleeve can be plenty wide and still do it — which is why letting the sleeve out changes nothing.
Pitch is genuinely hard to get right remotely, and I would rather say that plainly. Where a remote order gets it right, it gets it from a relaxed arm-length measurement plus a photo of your natural stance — not from a number typed into a box.
What are the signs a suit jacket is too tight?
Here is the checklist, with real comments from tailoring videos — including videos about Asian tailor shops, my own industry. A diagnosis you only apply to competitors is not a diagnosis.
| What you see | What it means | Fixable? |
|---|---|---|
| Stress lines radiating from the top button toward the armpit | Not enough chest ease. Under a Bangkok tailor video: "The front is too narrow and too short in the torso."4 | Partly — only with allowance in the side seams |
| Lapels lift and fold away instead of lying flat | Front too narrow across the chest. "You can see the jacket is too tight on the body when the lapels dont sit flat on the chest and fold up like that."3 | Rarely — a front-panel problem |
| Chest gapes open on small movements | Chest circumference right, balance or armhole wrong. "Every tiny movement makes the chest gape."3 | Sometimes, with a chest and shoulder rework |
| The whole jacket lifts when your arms go up | Armhole too low and too wide.2 | No — a smaller armhole means recutting the sleeve and body |
| Puckered shoulders, sleeves visibly strained | Sleeve head badly set or biceps too narrow. Under a Hoi An tailoring video: "Shoulders are puckered, and the sleeves cut way too tight."6 | Sleeve width sometimes; shoulder almost never |
| You cannot fold your arms or clap without the seams protesting | Back width too narrow. "If I were to clap the jacket would have exploded, busted at every seam."9 | No, if the centre-back seam has no allowance |
And the ten-second in-store test that beats all of them: put the jacket on, button it, and reach forward as if to shake a hand slightly too far away. If the collar leaves your neck, the armhole is too low. Then raise both arms to shoulder height; if the hem climbs, same verdict. Buttoned — the fair version of the test that video should have run.
Does fused versus canvassed cause the pulling?
Mostly no — and I say that as someone whose shop makes half-canvas jackets and could easily sell you the opposite story. Canvas is an internal layer of horsehair and wool that lets the chest mould to you and hold shape after cleaning; fusing is glue, stiffer and liable to bubble.78 Real differences, and they matter for how a jacket ages and drapes. But they are differences in the chest lining. The armhole is a hole: its height, its width and the sleeve pitch set into it are drawn on paper by whoever cut the pattern, long before any canvas appears. A fused jacket with a high armhole moves better than a full-canvas jacket with a low one.
Most people cannot pick fused from half-canvassed by eye.11 Everyone can feel a low armhole within a minute of wearing it. That tells you which one does more work in your daily experience of the suit. Full breakdown: half canvas vs full canvas vs fused; Suitsupply's own explainer is a fair account of what canvas does.10 Just do not expect canvas to buy range of motion.

Can a tailor let out a suit that is too tight?
A little — much less than people hope. A jacket gives back only what the maker left inside the seams, and that is a deliberate, finite amount.
| Area | Can it be let out? | Realistic gain |
|---|---|---|
| Side seams / waist | Usually, if allowance was left | An inch, sometimes two, around the body |
| Centre back seam | Often | Under an inch, and it moves the vents |
| Sleeve width | Sometimes | A little; can distort the sleeve head |
| Sleeve length | Usually, both ways | Limited by the turn-back inside the cuff |
| Shoulders | Effectively no | Nothing — a rebuild, not an alteration |
| Armhole (higher / smaller) | No | Nothing — requires recutting body and sleeve |
| Chest width across the front | No | Nothing — the front panel is the size it is |
So: too tight in the waist is a minor job. Too tight in the chest, shoulders or armhole is not a job at all — it is a different jacket. That is why "buy big and have it taken in" is decent advice, "buy small and have it let out" almost never is, and even a generous free-alterations offer cannot rescue the problem you searched for.

How do we try to get this right, and where we can still get it wrong
Nathan Tailors is in Hoi An, Vietnam. We cut only from our own cloth library — we do not work with fabric a customer brings in — and our suits run $149 to $309, garment only, as of September 2026, shipping quoted separately. In Hoi An it is two days; remotely, a three to four working-day make and two to three weeks shipped worldwide. On the armhole, three things matter:
- We ask for the measurements that decide the armhole, not just the ones that decide the size. Chest, shoulder, back width and biceps together set it; chest alone does not. Our guided measurement studio walks you through them one at a time with a photo check; written guides: chest, shoulder, biceps, sleeve, back width.
- Volume is the real advantage, and it is not romantic. Linda's cutters set sleeves into Western shoulders every day. A tailor taking three orders a week sees less variety in a year than ours see in a month — and armhole and pitch are exactly the skills repetition on unfamiliar bodies buys you.
- We leave seam allowance and send spare cloth so a tailor near you can adjust what is adjustable, at your cost. We do not offer a remake guarantee, and I would be wary of a shop that did — half the things that go wrong cannot be fixed by anyone, at any price, on a finished jacket.
Now the against-interest part. The "puckered shoulders, sleeves cut way too tight" comment in the table above is about a Hoi An suit.6 And "thai tailors make their suits (and shirts) slightly too tight" is fair criticism of a real regional habit.3 Southeast Asian tailoring often defaults to a closer cut than Western customers expect — a listening problem, not a price problem. So if you order from us, or from anyone here, say this out loud: "I want a high armhole and enough chest ease to reach forward buttoned." It is the most useful sentence in this post.
So what should you actually do?
Already own the pulling jacket? Check the waist — the only cheap fix — and accept the armhole. Buying? Run the buttoned reach test before you pay, at any price. Going custom? Specify armhole height, chest ease and shoulder slope rather than hoping for them.
General fit standards: how should a suit fit. When a made-to-measure order misses: what if your custom suit doesn't fit. The range and the cloth: custom tailored suits. No hard sell — a suit you can raise your arms in beats a suit from any particular shop.
Come by 127 Tran Hung Dao Street if you are ever in Hoi An. Linda will look at your shoulders for two seconds, tell you which one sits lower, then ask why you are so handsome. Both statements are sincere. Only one is a measurement.
