How Should a Suit Fit? Straight Talk From 30 Years on the Men's Floor

If there's one question I hear more than any other on the men's floor, it's this: how should a suit fit? I've spent 30 years handing suits to men in St. Louis, and I can tell you the right fit isn't about looking like a model. It's about not fighting the fabric. Most guys wear suits two sizes too big because they think comfort means extra room. It doesn't. A suit that fits gives you room to move without cloth pooling at the shoulder or sagging across the back.

Start With the Shoulders

If you're asking how should a suit fit, start here. The shoulder seam should sit right at the edge of your natural shoulder bone, not creeping down your arm and not pulling when you raise your hand. Run your hand across the top of the jacket. If you feel a bump where the padding ends before your shoulder does, the jacket is too narrow. If you feel a hollow, it's too wide. A tailor can adjust a lot of things, but he can't add fabric to the shoulders. This is the one measurement that has to be right before you leave the store.

Jacket Length and Sleeves

Jacket length is next. With your arms hanging at your sides, the jacket should cover your rear end and end around the middle of your thumb. The old rule was to let the jacket meet the curve where your fingers meet your palm. Any shorter and it starts to look like a casual blazer. Any longer and it looks like a hand-me-down. Sleeves should show about half an inch of shirt cuff, and the jacket sleeve should end at your wrist bone, not halfway down your hand.

Sleeve problems are the most common thing I see. A customer will look in the mirror and say the sleeves feel fine even though his cuff is buried. That's a simple fix, but check it before you buy. When in doubt, choose the size that hits your shoulder correctly and shorten the sleeves.

Trousers: Get the Break Right

Pants are an easier fix, but men still miss it. The back of the trouser should break just once on the top of your shoe. If fabric stacks at your ankles, the pants are too long. If they hang above the shoe and show sock, they're too short. For most guys, a regular break works. If you like a cleaner look, the pant should still graze the top of your shoe when you walk.

The Jacket Should Close Without Pulling

Now do the button test. Button the jacket and put your fist between the button and your chest. A fit that works gives you that much room without pulling. If you can't get a fist in, it's too tight. If you can fit two fists, it's too big. The lapels should lie flat. If they bow out or form an X-shaped pull, that size isn't yours. It doesn't mean the suit is bad.

What a Tailor Can and Can't Fix

A good tailor can take in a waist, taper a trouser leg, shorten sleeves, and adjust the jacket sides. In most cities, a solid alterations job runs $40 to $75, and it's the smartest money you'll spend. I've watched men buy a $300 suit off the rack, put another $50 into the tailor, and walk out looking like they spent three times that. Trust the shoulders and let the tailor handle the rest.

The honest answer to how should a suit fit? It should fit close enough that a tailor only needs to make adjustments, not rebuild it. I see a guy every season grab a jacket that fits in the chest but sags in the shoulders, skip the tailor, and never wear the suit. A $250 suit with a $50 trip to the tailor beats a $500 suit that's the wrong size.

Check the Back and Collar

Turn around in the mirror. A jacket that fits should lie smooth across your upper back. If you see an X of wrinkles between the shoulder blades, the jacket is too tight in the back. If the collar stands away from your neck when you button the top button, that's a sign the jacket is too small through the chest, even if the shoulders look right. These are the details I point out to customers who say close enough. Close enough is how the wrong suit ends up in the back of a closet.

The Fitting Room Rule

So how should a suit fit when you're standing in front of the mirror? Here's the checklist I give every man: shoulders first, then the button test, then sleeve length, then trouser break. Move around in it. Sit down. Reach for something on a high shelf. If the jacket binds or the pants pull, it's not the right fit.

One thing I tell every customer: try it on. That's what the fitting room is for. Don't buy based on the tag size. A 42 regular from one company can fit like a 40 from another. The numbers don't matter. The fit on your body does.

Bottom line: how should a suit fit? It should fit well enough that you forget you're wearing it. If the shoulders are right and the chest doesn't pull, the rest is a short trip to the tailor. Spend the money there, and you'll have a suit that works for a wedding, an interview, a funeral, and dinner out. That's just good sense from a man who has handed out a lot of suits.
