How a Suit Should Fit: A Simple Checklist for Men

A good fit makes an affordable suit look expensive. Use this head-to-toe checklist for shoulders, chest, sleeves, pants and length before you buy or visit a tailor.

A suit that fits well looks sharper than an expensive suit that does not. Most men buy jackets that are too big and pants that are too long, and the result looks borrowed. The good news is that fit is easy to check once you know what to look for, and a tailor can fix most problems at a reasonable cost.

Use this checklist from top to bottom.

1. Shoulders: the most important check

The shoulder seam should end exactly where your shoulder ends. Look in the mirror from the front and the side.

  • Too big: the seam hangs past your shoulder and you see a dent in the sleeve below it.
  • Too small: the fabric pulls across your upper back and the sleeve head looks tight.

Shoulders are very difficult and expensive to alter. If the shoulders do not fit, do not buy the jacket, however good the price.

2. Collar

The jacket collar should rest against your shirt collar without a gap. If it stands away from your neck, the jacket is fighting your posture or the cut is wrong for you.

3. Chest and button

Fasten the top button (or the middle one on a three-button jacket). The jacket should lie flat on your chest.

  • Too tight: you see an "X" of creases pulling from the button.
  • Too loose: you can fit more than a flat hand between the jacket and your chest easily, and the fabric billows.

4. Jacket length

A classic jacket covers your seat. A simple test: stand straight with arms relaxed, and the jacket hem should end around the middle of your hand. Modern cuts are slightly shorter, but if the jacket ends above your belt line, it is too short.

5. Sleeve length

With arms relaxed, about a quarter to half an inch of shirt cuff should show beyond the jacket sleeve. This small detail instantly makes a suit look tailored. Sleeves are usually easy to shorten or lengthen.

Bring your shirt and shoes to the fitting. The right shirt shows how much cuff appears, and your shoes determine the correct pant length.

6. Pant waist and seat

Pants should sit comfortably at your waist without a belt doing all the work. The seat should be smooth — not baggy, and not so tight that the pockets flare open.

7. Pant leg and break

The "break" is the fold where the pant meets the shoe.

  • No break: hem just touches the shoe; modern and clean, best with slim pants.
  • Slight break: a small single fold; the most versatile choice.
  • Full break: a deep fold; traditional, and can look sloppy on slim cuts.

For most men, a slight break looks best. The hem should never pool around the ankles.

What a tailor can and cannot fix

Usually easy Possible but costly Avoid
Sleeve length Taking in the jacket body Shoulder width
Pant hem Shortening a jacket a little Making a jacket longer
Pant waist (small change) Narrowing pant legs Fixing a collar gap from bad cut

Choosing your first suit

If you are buying one suit to cover interviews, weddings and formal work events, choose navy or charcoal in a medium-weight wool or wool blend. Both colors suit almost every skin tone, look smart in daylight and evening, and pair easily with white and light-blue shirts.

A two-button, single-breasted jacket with notch lapels is the most versatile style. Flat-front pants suit most body types.

Caring for your suit

  • Hang the jacket on a wide, shaped hanger to protect the shoulders.
  • Give the suit a day of rest between wears so the fibers can recover.
  • Brush it with a clothes brush instead of dry-cleaning too often — chemical cleaning wears out fabric.
  • Empty the pockets so they keep their shape.

The takeaway

Start with the shoulders, then check collar, chest, length and sleeves before moving on to the pants. Buy the suit that fits your shoulders, and let a tailor handle the rest. A modest suit, perfectly fitted, will always look better than a designer suit that hangs wrong.
