While you may have your measurements memorized, the numbers don't always add up. No two manufactures shirts fit exactly alike. Try one before you buy it, take an honest look at yourself in the mirror and follow these guidelines for finding the perfect fit. Even Better get your shirts custom-made.
The Torso:
There's a lot of middle ground between too loose and too tight. So, just Find it. The shirt should be snug in the chest, but not so snug that the fabric pulls between the buttons.
The Back:
For those guys who are beefier, they should get a shirt with boxed pleats or side pleats in the back. As it gives a little room without the extra volume.
For the guys with a slimmer builds, should opt for a fitted styles that contour down towards the waist.
Either way, the seams of the shirt should lie on the curve of your deltoids (the muscles behind your shoulders, the ones you'd work if you did push ups).
The Waist:
Sit down while you're wearing the shirt. It should skim your waist but leave just enough room to give when you're seated.
The Neck:
The golden rule hasn't changed. You should be able to comfortably fit two fingers in between your neck and the collar of the shirt when it's buttoned.
The Sleeves:
The Cuff of the shirt should fall in the crook between the base of your thumb and your wrist.
The Tails:
The tails should be long enough to lie under your rear end when you're seated. That will prevent the shirt from riding up or coming untucked. It will also give you better posture.
Rules of Thumb:
* Shirts should never ballon when tucked into your pants.
* Buttons lie flat and fabric does not pull between them.
* Collar Fits snugly whether open or closed.
