To find out your chest size, take a tape measure and wrap it under your armpits at the fullest part of your chest. Stand straight and don’t puff out your chest. Keep the tape measure taut, but not constricting. It shouldn’t be squeezing down your chest, just resting.
In between sizes? We recommend that you go a size up.
