If you only check one thing when you try on a suit jacket, check the shoulders. Sleeves can be shortened, waists can be taken in and trousers can be hemmed, but the shoulder is the frame everything else hangs from. When it's wrong, nothing below it looks quite right, and it's the hardest part of a jacket to fix after the fact.
Here's how a suit jacket should fit in the shoulders, how to check yours in front of a mirror, and why it's the first thing to get right.
The shoulder seam of a jacket should end right at the edge of your natural shoulder, the point where the top of your arm bone meets the shoulder. Look for a smooth, clean line from the collar out to the top of the sleeve. No dents, no bumps, no fabric hanging past the edge.
A simple way to find the right spot: stand next to a wall, turn sideways and lean your shoulder into it. If the jacket's shoulder pad touches the wall before your arm does, the shoulders are too wide. If your arm hits first and the fabric pulls, they're too narrow. When it fits, the pad and your shoulder meet the wall together.
This is very common with off-the-rack jackets. Men often size up to fit the chest or stomach, and the shoulders come along for the ride.
Most alterations work at the edges of a garment: hems, cuffs, side seams. The shoulder sits at the structural center of the jacket. The collar, the sleeve and the canvas or interfacing all meet there, so changing the width means taking the jacket apart and rebuilding a big piece of it. Even when it's possible, it's expensive, and the result rarely looks as clean as a jacket that was right to begin with.
That's why the rule among tailors is simple: fit the shoulders first, then tailor everything else. If a jacket fits your shoulders, a good tailor can usually adjust the waist, sleeves and length. If it doesn't, you're almost always better off walking away.
Shoulder width is only half the story. Every man also has a shoulder slope (how steeply the shoulders drop from the neck) and a posture (how far forward or back he carries them). One shoulder is often a little lower than the other, especially on the dominant side.
A ready-made jacket assumes average slope and perfect posture. If your shoulders are square, you'll see wrinkles running toward the collar. If they slope more than average, you'll see diagonal folds running from the collar toward the armpits. These lines aren't a sizing problem. They come from the shape of the jacket not matching the shape of the man inside it.
With a made-to-measure jacket, the shoulders aren't a compromise between your chest size and a size chart. At Pearce Bespoke Detroit we take more than 20 body measurements and note your shoulder slope and posture, then build the jacket from a refined base pattern adjusted to you. The shoulder is set for your frame, and the chest, waist and sleeves follow from there.
It's also how we pair it with the rest of the fit. Once the shoulders are right, details like sleeve length and how the jacket closes at the waist fall into place much more easily. Alterations are included, and every garment is backed by our perfect fit guarantee.
This matters most for men who wear a jacket all day: attorneys standing to address the court, advisors in back-to-back client meetings, executives presenting to a board in Troy or Southfield. A jacket that fits through the shoulders looks composed when you stand, sit and reach, and you stop thinking about it.
If your current jackets fail the shoulder test, the fix usually isn't another alteration. It's a jacket built around your frame. Pearce Bespoke Detroit is a mobile custom clothier.
