How to measure your shirt size
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.

OUT: The measuring tape needs to be loose enough to slide around easily. Consider having someone take your measurements for you.
