Suits for tall and slim men. Long is not the same as long enough

Jacket advice for tall men is everywhere. Trouser advice is not, and the trouser is where the frustration actually lives.

The inseam and the waist are graded together. Find a trouser that fits your waist and the leg is short. Find one long enough and the waist is wide. There is no size for a 32 waist with a 36 inseam, because a rack trouser assumes the two move in step, and on a tall lean man they do not.

And the only two shapes on offer are wrong. Skinny, which clings to a long thin leg and reads as leggings, or straight and baggy, which hangs like a curtain and removes whatever shape you had. Almost nothing in between exists in a size that also reaches your shoe, because the taper is drawn for an average leg length and then stretched or cut to reach yours.

A trouser cut to your inseam is tapered across your leg rather than across someone else's. The taper begins where your knee actually is. That single fact is why a custom trouser on a tall lean man reads as clean rather than as either extreme.

About an inch and a half. That is the standard difference between a regular and a long in body and sleeve. If your arms run three inches past what a regular carries, one long size does not reach and two long sizes do not exist.

And every inch of width comes with it. Chest, waist, shoulder, sleeve circumference. A lean man in a long size is wearing a jacket cut for a heavier man of the same height, which is why it hangs rather than follows.

The jacket length is the part that ruins it. Sleeves are what you notice first and length is what the room notices. A jacket that stops above your seat makes the torso look short and the legs look disproportionate, and a jacket that runs long on a tall frame reads as borrowed. On a tall man there is more distance to get wrong, which is why the measurement matters more here rather than less.

A client came to us with the same problem in two garments. Jackets either fit and had sleeves that stopped well short, or had sleeves that reached and did not fit anywhere else. Trousers ran the same way: correct at the waist and short at the ankle, or long enough and wide through the leg. He had been choosing which failure he could live with for years, which is what you do when the chart offers no third option.

There is a specific failure on a long thin arm that almost no article covers, and every tall lean man recognizes it immediately.

A sleeve cut narrow to avoid looking baggy on a thin arm has no cloth to spare over the elbow. Standing still it looks correct. Bend the arm and it binds, and the fabric pinches at the point of the bend because there is nowhere for it to go. The sleeve was measured on a straight arm and worn on a bent one.

The correction is not simply cutting the sleeve wider, which returns you to the baggy version of the problem. It is three measurements rather than one.

The bicep is measured and the sleeve is sized to it. Not derived from the chest, which is what a rack sleeve does. This sets the top of the sleeve to your actual arm rather than to the arm a 40 chest is assumed to have.

The taper runs from that number down. A sleeve that starts correct at the bicep and narrows across its length keeps its shape without binding, because the width is distributed rather than uniform.

The cuff is specified independently. The opening at the wrist is chosen rather than inherited from the sleeve length, which is what makes the taper functional instead of decorative. A cuff sized to your wrist finishes the line the bicep started.

Done together, the sleeve fits at rest and still fits bent. Done as one measurement, it can only do one of those.

A lean frame gives the cloth nothing to sit on. Left unshaped, a jacket on a tall thin man hangs straight from the shoulder and reads as a coat rather than a suit.

The chest and waist are cut as two numbers. Suppression through the waist gives the jacket a line rather than a drop, and on a lean frame that line is the difference between tailored and draped.

The shoulder is cut to your shoulder. On a narrow frame a shoulder that extends past the joint collapses the whole silhouette, because every line below it starts from the wrong place.

Pleats are chosen, not defaulted. How many and how deep, set against your build rather than against the house cut, so the trouser has shape at the hip without adding bulk you do not need.

The result is a V that reads through the jacket rather than a garment that falls from the shoulders. On a lean tall frame that shaping is what makes the build look considered rather than incidental.

Everything above applies to a blazer or a sport coat, because the problem is the jacket rather than the suit. Sleeve length, jacket length, shoulder width and the elbow bind all behave identically, and a long size gets them wrong in the same order.

A custom blazer or sport coat starts from the same measurements and starts at $499. The custom blazers page has the details.

Made to measure starts at $999. In named mill cloth it starts at $1,500, which is also where canvassed construction begins. The full ladder is on the cost page.

Three steps, and you never leave your house.

1. 1. We come to you and measure. Height, torso, sleeve, bicep, wrist, chest, waist, inseam, rise. Every dimension a long size decided for you gets measured instead.
2. 2. Your suit is cut to those numbers. 4 to 8 weeks.
3. 3. We come back and fit it. Any adjustment happens on you, at your home or office.

Being tall and lean is a proportion, and made to measure is built for proportion. Bespoke, from $5,000, exists for shape a graded pattern cannot reach: a dropped shoulder, a stance that pitches forward, an asymmetry. Height and build on their own are not those. If something else is going on as well, the comparison page explains where the line falls.

• The jacket that fits your chest has sleeves that stop short.
• The jacket with sleeves that reach swallows you everywhere else.
• Trousers that fit your waist are too short, and the ones long enough are too wide.
• Your only two options have been skinny or baggy.
• Your sleeve pinches at the elbow when you bend your arm.
• You have been told to buy a long, and it was still wrong.

Any two of those and the problem was never your height. It was length and width graded as one number when they are two.
