The above chart indicates body measurements, not garment dimensions.
Calculate your own body measurements, then select the appropriate product size.
If your body measurements are between sizes, go down to the smaller size for a tighter fit, or up to the larger size for a more relaxed fit.

How to measure
Chest - Measure around your chest, under your armpits.
Waist - Measure around your waist, where you would normally wear your trousers.
