Walk through any office in America and you'll see it: good shirts worn badly. Shoulder seams drooping halfway down the arm. Collars floating an inch off the neck. Cuffs swallowing wrists. Most men wear their shirts a full size too big, and it's not their fault — nobody ever handed them the reference points.
Here they are. Five checkpoints, two minutes in front of a mirror, and you'll never buy the wrong size again.
1. The shoulder seam — the one that can't be fixed
The seam where the sleeve meets the body should end exactly where your shoulder bone ends. Run your finger along your shoulder: feel where the bone drops off? That's where the seam belongs.
Everything else on a shirt can be adjusted by a tailor for a few dollars. The shoulder cannot — not without rebuilding the shirt. If the seam droops down your arm, the whole shirt is too big, no matter how the rest feels. This is the first thing to check and the only dealbreaker.
2. The collar — the one-finger rule
Button the shirt to the top, even if you never wear it that way. You should be able to slide one finger between the collar and your neck — comfortably, without forcing it.
Two fingers of room means the collar will gape and slide all day. Zero fingers means a red pressure line by lunch and a subtle feeling of being strangled through your 2pm meeting. One finger. That's the spec.
3. The chest — the pinch test
Pinch the fabric at the fullest part of your chest and pull it away from your body. You want two to three inches of material between your fingers.
More than that and the shirt billows when you tuck it — the dreaded parachute. Less and every button strains when you sit down, which photographs even worse than it feels. Slim fit or relaxed fit, the pinch test holds; the cuts just distribute the room differently.
4. Sleeve length — the thumb landmark
Stand with your arms relaxed at your sides. The cuff should end right at the base of your thumb — where the wrist bone meets the hand.
If you wear a jacket, this length gives you the classic quarter-inch of shirt cuff showing past the jacket sleeve — the detail that separates "wearing a suit" from "wearing a suit well."
5. The hem — the raise-your-arms test
A shirt you plan to tuck needs enough length to stay tucked when you raise your arms — reach up right now, and if the hem pulls out of an imaginary waistband, it's too short. A shirt you wear untucked should end mid-fly: long enough to cover the waistband, short enough not to read as a nightshirt.
Where our shirts land
Every shirt in our collection is cut to these checkpoints, and each product page carries a fit tip for that specific cut — our slim dress shirt runs tailored through the chest, our relaxed button-down gives you room by design. Cross-check your measurements against the Size Guide once, and you're set for every order after.
Two minutes, five checkpoints. That's the entire skill.
