Be sure to keep the tape level and not too tight. To determine your chest size, wrap a measuring tape around your natural chest, just under the arms. To determine your waist size, wrap a measuring tape around your natural waist. Then use the chart below as a guide but allow for some variance based on how you prefer the garment to feel.
