How to use this chart. Start with your neck size, then check your chest and waist against the "Fits" rows. The "Shirt" rows are the measurements of the finished shirt. Ranges overlap on purpose: if you fall between two sizes, choose the smaller for a closer fit or the larger for more room.
ANeck: Measure around the base of your neck, where the collar sits.
BChest: Measure around the fullest part of your chest, under your arms.
CWaist: Measure around your natural waist, at the navel.
