Chest circumference
How women determine their chest circumference: Underbust circumference: Measure horizontally around your body under your chest. Chest circumference: Place the measuring tape horizontally on the largest part of your chest and measure the circumference.
How men determine their chest circumference: Measure under the armpits at the thickest part of the chest. For the best result, we recommend measuring directly on the body or wearing thin clothing for the measurement. Our size chart contains a nice drawing.
