How to measure your shirt size<br>Keep your body relaxed while taking your measurements. Do not puff out your chest, suck in your belly, or flex your muscles. If you do any of these, the measurements will not be accurate and the shirt will not fit.
Accurate measurements cannot be obtained while in a state of non-tension.
This is the opposite of what the paragraphs says or implies about being relaxed leading to a good fit.
