How to Measure a Shirt: Collar Around
Unbutton the shirt and spread it out on its back. Place one end of the measuring tape at the center of the button where the button stitching comes through to the inside of the collar band. Pull the collar tight so that any curve to the collar band becomes straight. Measure straight across the collar band to the far edge of the button hole. Round to the nearest ¼ inch.
Do not add extra to account for shrinkage. We will do that for you.
